In this talk, we want to consider some class of non-holomorphic Jacobi forms and its relationship to modular forms. This work was motivated by the paper “Taylor coefficients of non-holomorphic Jacobi forms and applications”, by Kathrin Bringmann, which had been motivated by Zwegers’ work on so-called Appell’s functions. We study Appell`s function more, and applying the ideas arising from harmonic Maass forms, we relate some series coming from combinatorics. Zoom Meeting ID : 836 3968 3307 -서울대학교 기초과학연구원 중점연구소 지원
