Adventures In Gambling Mathematics: Selected Short Subjects

Speaker:  Mark Bollman
Professor and Chair, Department of Mathematics and Computer Science
Mathematics & Computer Science
Albion College
Albion, MI

Abstract: 
Games of chance provide a rich source of questions in applied probability. The field of casino game development, much like gambling itself, is a highrisk proposition that carries a very small probability of high reward for the designer of a successful new game. This talk will examine a number of nonstandard casino and lottery games and the mathematics involved to analyze them. Examples are drawn from card games, dice games, and lotteries.

Undergraduate Research in Combinatorics/Graph Theory

Speaker:  Heather Jordon
Associate Professor
Mathematics and Computer Science
Albion College
Albion, Michigan

Abstract: 
In last week's seminar, opportunities for funding for summer research projects were discussed but what would you actually DO in a summer research project? In this talk, several projects that undergraduate students worked on during the Spring 2016 semester in the mathematical area of combinatorics/graph theory will be discussed. We'll describe the projects, talk about the process, and what the students were required to do. The students did this work as part of a course entitled "Introduction to Undergraduate Research in Mathematics" at Illinois State University. Eight students participated who were all math majors; some pursuing secondary teaching and some going on to graduate school.

Title: 
Group Testing: From Syphilis to Sparse Fourier Transforms

Speaker:  Mark Iwen
Assistant Professor
Dept. of Mathematics, and Dept. of ECE
Michigan State University
East Lansing, Michigan

Abstract: 
Periodic functions with a relatively small number of energetic Fourier coefficients appear in many applications including communication protocols, image processing problems, and numerical methods for solving some partial differential equations. In this talk we will discuss some algorithms for recovering such functions more quickly than possible via traditional discrete Fourier transform methods. In the process we will encounter world war two history, number theory, combinatorics, error correcting codes, and movie stars.

Title: 
Answering Condorcet's Omission

Speaker:  Tomas McIntee
Mathematics
Virginia Tech
Blacksburg, VA

Abstract: 
M. J. A. N. de Caritat, the Marquis de Condorcet, raised concerns about the Borda Count in "Essay on the Application of Analysis to the Probability of Majority Decisions" (1785), introducing several concepts that now bear the name of Condorcet; in particular a voting paradox and voting criteria. One of the latter was used by M. J. A. N. de Caritat to criticize a positional voting method introduced by contemporary J. C. de Borda in 1770. In this presentation, the question of how probability applies to the voting paradox and the application of the related criteria to positional voting rules is raised, leading to a spectrum of answers of varying plausibility. The most plausible answers can be seen to be those given for Borda's voting system.

Title: 
Not so sinister after all: How mathematical models can explain the resilience of the lefthanded minority

Speaker:  Mark. J Panaggio
Assistant Professor
Mathematics
Hillsdale College
Hillsdale, MI

Abstract: 
Every human population in recorded history has been predominantly righthanded with a small lefthanded minority that persists often despite intense societal pressure to conform. Although numerous explanations for individual handedness have been proposed, none of these explanations can account for this populationwide bias. In this talk, I will present a minimal mathematical model describing competition between groups of left and righthanded individuals in a population that can explain our righthanded world. Analysis of the equilibrium states of this dynamic model will shed light on why most humans are righthanded, why most animals are not, why lefthanded athletes overachieve in baseball, why they underachieve in golf and will demonstrate that even simple models built using tools from calculus can provide meaningful into the behavior of complex systems.

Title: 
Critical Thinking and Debugging Software

Speaker:  James T. Streib
Professor of Computer Science
Computer Science
Illinois College
Jacksonville, Illinois College

Abstract: 
This presentation examines various difficulties that beginning programmers sometimes encounter when attempting to debug software. Unfortunately, some beginning programmers make repetitive guesses in an attempt to solve a problem. First, this presentation examines how to break this cycle of guessing. Second, although there are a number of definitions of critical thinking, this presentation will examine one of the original ones proposed by John Dewey. Next, it looks at how critical thinking can be employed when walking through code to debug a logic error. Lastly, it offers some suggestions and provides some closing thoughts. The audience for this presentation is students, tutors, lab assistants, teaching assistants, and instructors, especially ones new to their roles. For those who may already possess good debugging skills, it might help articulate what they have already been practicing.

Title: 
The Mathematics of Apportionment in U.S. Presidential Primaries and the General Election

Speaker:  Michael A. Jones
Associate Editor
Mathematical Reviews
Ann Arbor, MI

Abstract: 
Apportionment is a mathematical way to round integers proportionally. Although well known to determine how many seats each state receives in the U.S. House of Representatives, apportionment methods are also used in the U.S. presidential primaries and the general election. We'll examine the geometry of two types of paradoxical behavior that may occur in these settings, using real data when appropriate. We'll also touch on some recent proposed laws and how they would affect the paradoxical behavior.

Title: 
How does variation in life history strategies effect long term population trajectories of eelgrass?

Speaker:  Stephanie Thurner, '17
Senior Mathematics Major
Mathematics
Albion College
Albion, Michigan

Abstract: 
Seagrasses are important habitat forming marine angiosperm in coastal ecosystems. Contemporary
declines in seagrass habitats worldwide warrant understanding factors that may allow managers to
predict change and recovery in these habitats. In the Pacific Northwest, eelgrass (Zostera marina) forms
these critically productive meadows and has experienced instances of localized population decline.
These site specific declines are often persistent, lacking natural recovery. In an attempt to combat these
declines, human aided restoration is endeavored with worldwide success rates around 30%. Eelgrass
reproduces using two different life history strategies, asexual and sexual reproduction, with varying life
history strategies between populations. It is unknown how variation in life history strategy affects the
long term population trajectories of eelgrass. In this study we develop a stagebased matrix population
model, parameterized by field data collection, previous experiments, and data mining to map the effects
of life history variation on population growth. The eelgrass lifecycle was mathematically defined as three
stages (vegetative shoots, flowering shoots, and seeds) as well as by the vital rates describing the
transitions between these stages (branching rate, flowering rate, fecundity, germination rate, and
seedling survival rate). By analyzing populations with variations in sexual and asexual reproduction and
validating the model through a comparison with a long term field study experiment, we saw that the
model is a highly conservative estimate for solely sexually reproducing populations, and an over
estimate for populations with asexual reproduction. When the field recovery experiment was analyzed,
we could also see that recovery of a population back to initial population levels after a disturbance is
different when density is determined spatially rather than by looking at the entire area. Further data
collection and refinement of vital rates as well as the addition of other environmental conditions will
increase the accuracy of the model and help inform management and conservation strategies.

Title: 
Monte Carlo Integration and Implementation in the R Programming Language

Speaker:  Ethan Sutton, '17
Senior Mathematics Major
Mathematics
Albion College
Albion, Michigan

Abstract: 
This integral can not be solved analytically and therefore the solution is found using a numerical method" is something occasionally stumbled upon in the textbook of a first or second year calculus student. In this talk we will examine one of these numerical methods used to solve complex integration problems using a method known as "Monte Carlo Integration." This method is particularly useful for integration of higher dimensional functions but also computationally intensive making it very inefficient without the aid of the computer. Therefore, an implementation of this method in the R Programming Language will also be demonstrated.

You've been doing geometry wrong?!

Speaker:  Stephen Oloo
Visiting Assistant Professor
Math and CS Department
Kalamazoo College
Kalamazoo, MI

Abstract: 
I will introduce projective space and discuss how it is a better setting for doing geometry than our familiar euclidean space. In truth, this discussion will really be an excuse to introduce interesting mathematical ideas such as compactifications and moduli spaces. We may even delve into some algebraic topology.

Polygons, Polyhedra, and String Theory

Speaker:  Ursula Whitcher
Associate Editor
Mathematics Reviews
American Mathematical Society
Ann Arbor, Michigan

Abstract: 
If you have a rubber band and a pegboard, how many polygons can you make that have only one peg in the center? The answer to this question is highly interesting to string theorists, who use shapes like these to write equations for the predicted "extra" dimensions of the universe. We'll talk about the way mathematicians use intuition from string theory to make mathematical discoveries.

A walk through Algebraic Curves

Speaker:  Chris Creighton, '11
Graduate Student
Department of Mathematics
Purdue University
West Lafayette, Indiana

Abstract: 
The aim of this talk is to give an introduction to Algebraic Curves, that is, the zero set of some polynomial equation in two variables. We'll mosey through varieties in general and stroll through why the coefficients of the polynomial matter. The path of choice is concepts of nonsingularity and rational functions on the curve. If time, we can go onto the side path of divisors and related topics.

Title: 
What would you pay for a guarantee to sell X for Y?

Speaker:  Darren Mason
Professor
Mathematics & Computer Science
Albion College
Albion, MI

Abstract: 
The current price of Apple stock is $131.74. You are offered a chance to enter into the following agreement:
 If tomorrow Apple stock increases to $133.22, you receive nothing;
 If tomorrow Apple stock decreases to $129.88, you receive $1.12.
you receive $1.12.
Assuming that you know that starting with the initial stock price of $131.74, Apple stock has a 60% chance to increase to 133.22 and only a 40% chance to decrease to $129.88, how much are you willing to pay for this agreement? Or, in other words, what is a fair price to charge for this "contract"?
The above scenario is an example of a financial option called a "put" stock option, which gives the owner the right, but not the obligation, to sell an asset to another person at a particular time (or times) in the future. In the above case, you are guaranteed that you can sell Apple for $131, regardless of stock value. How to fairly price such options, as well as other types of financial derivatives, is an interesting aspect of mathematical finance and stochastic calculus, a field that has its roots in a French mathematical thesis from 1900, resulted in the 1997 Nobel prize in economics, and provides a concrete use for such oddities of real analysis as continuous functions that are nowhere differentiable.
By the end of this talk you should be able to fairly price the above Apple stock option, as well as understand and price more complicated financial derivatives, within a universe where time discretely ticks by.

Title: 
The NoSided Möbius Band

Speaker:  Robert Messer
Mathematics and Computer Science
Albion College
Albion, Michigan

Abstract: 
Wikipedia says, "The Möbius band is a surface with only one side and one edge." We will construct some Möbius bands and verify this observation. But is it possible for a Möbius band to have two sides? We will see that the number of sides of a geometric object is not an intrinsic property of the object but instead depends on the space around it. In 1946, Martin Gardner wrote a short story about topologists who folded themselves into nosided Möbius bands. Where can we find one of these?

Title: 
Ramanujan's Life and Notebooks

Speaker:  Bruce Berndt, '61
Professor
Mathematics
University of Illinois
Urbana, Illinois

Abstract: 
Srinivasa Ramanujan was the greatest mathematician in the history of India. He was born in southern India in 1887 and died there in 1920 at the age of 32. He had only one year of college, but his mathematical discoveries, made mostly in isolation, have made him one of 20th and 21st centurys' most influential mathematicians. An account of Ramanujan's life will be presented. Most of Ramanujan's mathematical discoveries were recorded without proofs in notebooks, and a description and history of these notebooks will be provided. A lost notebook of Ramanujan was found in 1976. We shall also give a history and description of the lost notebook. The lecture will conclude with a brief survey of the areas of
mathematics to which Ramanujan made profound contributions.

Game. SET. Line

Speaker:  David Austin
Professor of Mathematics
Mathematics
Grand Valley State University
Allendale, MI

Abstract: 
SET is a simple card game based on pattern recognition that can challenge both children and adults. It also has a surprisingly rich underlying mathematical structure that ties together ideas from a range of subjects including geometry, combinatorics, and linear algebra. In this talk, we will consider some simple questions that arise when playing SET and investigate the mathematical ideas that provide answers. We will also describe some recent and deep work from last year that gives a surprising result about a generalization of SET.

Title: 
Julia Robinson and Hilbert's Tenth Problem

Speaker:  Zala Films (Video)

Abstract: 
"From the Julia Robinson and Hilbert's Tenth Problem is a video portrait of Julia Robinson. The biographical documentary features a heroine, captivated by the lure of unsolved mathematical problems, who rises against formidable obstacles to assume a leading role in her field. Robinson's pursuit of these problems, and one in particular—Hilbert's tenth problem—brought her face to face with critical developments in 20th century mathematics. The film presents Robinson's life in the context of the 70year search for a solution to the tenth problem.
Julia Robinson's work hinged on the ideas of key protagonists in the history of mathematics and logic: David Hilbert, Alfred Tarski, Alan Turing, and Kurt Gödel, among others. The film interweaves the personal story of this important figure in American mathematics with the discovery of new ideas that led to the development of computers."
