摘要：

We describe the non-perturbative trans-series, at both weak-and strong-coupling, of the large N approximation to the beta function of the Gross-Witten-Wadia unitary matrix model. This system models a running coupling, and the structure of the trans-series changes as one crosses the large N phase transition. The perturbative beta function acquires a non-perturbative trans-series completion at large but finite Nin the 't Hooft limit, as does the running coupling. (C) 2018 The Authors.
