Description:
Let k be an algebraically closed field, and let f:X→X be an endomorphism of a separated scheme of finite type over k. We show that for any ℓ invertible in k, the alternating sum of traces ∑i(−1)itr(f*|Hi(X,ℚℓ)) of pullback on étale cohomology is a rational number independent of ℓ. This...
