Seminars for the week of November 5, 2007
Colloquium
Thursday, 3:20, in VinH 16Professor Pierre Berthelot
of Universite de Rennes 1/Ordway Visitor
will speak on
"Congruences mod q for the number of rational points of an algebraic
variety over a field with q elements"
Starting with classical results of Chevalley-Warning, Ax and Katz, it is known that, for certain algebraic varieties over a finite field k with q elements, the cardinality of their set of k-rational points is divisible by q. I will explain how Serre's Witt vector cohomology can be extended so as to define a cohomology with compact supports for arbitrary algebraic varieties over k, providing a general criterion for the existence of congruences modulo q on the number of k-rational points (joint work with S. Bloch and H. Esnault).
