Abstract:
I'll discuss a relationship between the following two objects arising from the spectral curves of hypergeometric differential equation and its confluent degenerations: The free energy compute by Eynard-Orantin's topological recursion, and BPS spectrum (degeneration of spectral networks) for the corresponding quadratic differentials computed by the algorithm of Gaiotto-Moore-Neitzke / Bridgeland-Smith. In particular, I'll show a simple formula expressing the topological recursion free energies as a sum over BPS states. My talk is based on a joint work with O. Kidwai.
