Title: Elliptic CY 3-fold, refined BPS states and weak Jacobi Forms

Abstract: We show that the all genus BPS on compact elliptically fibered Calabi-Yau manifolds can be written in terms of meromorphic Jacobi forms whose weight grows linearly and whose modular index grows quadratically with the base degree. If a suitable defined geometric index of a curve  class in the base is negative the  corresponding 6d-theory can be solved completly. This solves e.g. the BPS  spectrum of the E-string and related 6d theories.
