Hilbert quasimodular forms and Hilbert Jacobi-like forms

Authors: Min Ho Lee

Abstract:

Quasimodular forms and Jacobi-like forms generalize modular forms and Jacobi forms, respectively, and Hilbert quasimodular forms and Hilbert Jacobi-like forms are their extensions to several variables. They are linked to each other due to the fact that each coefficient of a Hilbert Jacobi-like form is a Hilbert quasimodular form. Given a Hilbert quasimodular form, we construct a Hilbert Jacobi-like form which has the given function as one of its coefficients. The resulting Hilbert Jacobi-like form generalizes the Cohen—Kuznetsov lifting of a modular form.

Keywords: quasimodular forms, Hilbert modular forms, Jacobi-like forms
