A new geometric description for Igusa's modular form
arXiv:1110.1997 · doi:10.1007/s12188-013-0077-z
Abstract
The modular form notably appears in one of Igusa's classic structure theorems as a generator of the ring of full modular forms in genus 2, being exhibited by means of a complicated algebraic expression. In this work a different description for this modular form is provided by resorting to a peculiar geometrical approach.
