Independence of ℓ and traces on cohomology

Let k be an algebraically closed field, and let [Formula: see text] be an endomorphism of a separated scheme of finite type over k. We show that for any [Formula: see text] invertible in k, the alternating sum of traces [Formula: see text] of pullback on étale cohomology is a rational number indepen...
