Geometric interpretation of Hermitian modular forms via Burkhardt invariants

Number Theory 2024-08-13 v3 Algebraic Geometry

Abstract

We give a complete theta expression of a pair of Hermitian modular forms as an inverse period mapping of lattice polarized K3K3 surfaces. Our result gives a non-trivial relation among moduli of K3K3 surfaces, theta functions and the finite complex reflection group of rank 55.
