We compute the number of rational points of classifying stacks of Chevalley group schemes using the Lefschetz–Grothendieck trace formula of Behrend for l-adic cohomology of algebraic stacks. From this we also derive associated zeta functions for these classifying stacks.

Abstract
We compute the number of rational points of classifying stacks of Chevalley group schemes using the Lefschetz–Grothendieck trace formula of Behrend for l-adic cohomology of algebraic stacks. From this we also derive associated zeta functions for these classifying stacks.File in questo prodotto:
