Enough injectives, derived functors. This talk explains the relation between the Lefschetz fixed point formula and the Weil conjectures. More precisely, the zeta In mathematics, the étale cohomology groups of an algebraic variety or scheme are algebraic analogues of the usual cohomology groups with finite coefficients.
