Abstract: In this paper we study a generalization to stacks of Fujiwara’s theorem on the traces of correspondences acting on the cohomology of varieties over finite fields. We explain how to define naive local terms in the stack-theoretic context and state a conjectural generalization of Fujiwara’s theorem in this setting. We prove the conjecture for correspondences arising from group actions.
