Étale duality for constructible sheaves on arithmetic schemes
Étale duality for constructible sheaves on arithmetic schemes
Abstract. In this note we relate the following three topics for arithmetic schemes: a general duality for étale constructible torsion sheaves, a theory of étale homology, and the arithmetic complexes of Gersten–Bloch–Ogus type defined by K. Kato (1986). In brief, there is an absolute duality using certain dualizing sheaves on …
