Description
This talk concerns the global aspects of the WKB analysis of meromorphic linear systems of ordinary differential equations with Poncar\'{e} rank 1. It proposes a connection between the WKB approximation of the monodromy data and the integral periods over the associated spectral curves, which generalizes the asymptotic and jump properties of Voros symbols in the exact WKB analysis of Schrödinger equations. It is based on a joint work with Anton Alekseev and Yan Zhou.
