Shifting local exponents of Picard-Fuchs operators

Algebraic Geometry 2026-03-25 v1

Abstract

We investigate the operation of shifting local exponents and study its effects on the monodromy representation of a one-parameter family of Calabi-Yau threefolds. The main result is a characterization of shifts of geometric operators which are also geometric. We use this description to construct some Picard-Fuchs operators with interesting properties.
