A short proof of de Shalit's cup product formula

Number Theory 2007-05-23 v1 Algebraic Geometry

Abstract

We give a short proof of a formula of de Shalit, expressing the cup product of two vector valued one forms of the second kind on a Mumford curve in terms of Coleman integrals and residues. The proof uses the notion of double indices on curves and their reciprocity laws.
