Explicit Deligne pairing

Algebraic Geometry 2021-06-14 v2

Abstract

We give an explicit formula for the Deligne pairing for a proper and flat morphisms f:XSf:X\to S of schemes, in terms of the determinant of cohomology. The whole construction is justified by an analogy with the intersection theory on non-singular projective algebraic varieties.
