Intersection numbers of twisted homology and cohomology groups associated to the Riemann-Wirtinger integral (2206.03177v2)
Published 7 Jun 2022 in math.AG and math.CA
Abstract: The Riemann-Wirtinger integral is an analogue of the hypergeometric integral, which is defined as an integral on a one-dimensional complex torus. We study the intersection forms on the twisted homology and cohomology groups associated with the Riemann-Wirtinger integral. We derive explicit formulas of some intersection numbers, and apply them to study the monodromy representation, connection problems, and contiguity relations.
