Abstract: We will explain a conjecture that expresses the BPS invariants (Gopakumar-Vafa invariants) for elliptically fibered Calabi-Yau threefolds in terms of modular forms. In particular, there is a recursion relation which governs these modular forms. Evidence comes from the polynomial formulation of the higher genus topological string amplitudes with insertions.
