Abstract
The purpose of this talk is to review Ecalle's seminal 1984 work about two kinds of resurgence phenomena, "equational resurgence" and "co-equational resurgence"; the latter is also called "parametric resurgence" or, in the context of WKB semi-classical approximation, "WKB resurgence" or "quantum resurgence" or "Voros resurgence". If time permits, we shall describe how the duality equational/co-equational works in the case of one-dimensional stationary Schrödinger equation with homogeneous potential.
