Title: | A cohomological approach to Serre's Minkowski-style bounds |
Speaker: | Giovanni Di Matteo (`06) Ecole Normale Superieure de Lyon (forthcoming) Lyon, France |
Abstract: | In recent years, Serre has adapted a classical theorem of Minkowski to give bounds for the ℓ-valuation of |G(k)|, where G is a reductive group or semi-simple of inner type. It was observed by Serre that these bounds may be recovered from ℓ-adic cohomology. We illuminate the cohomological approach in the case of G = GLn. |
