Resurgence Analysis of Meromorphic Transforms

英文摘要：

We consider meromorphic transforms given by meromorphic kernels and study their asymptotic expansions under a certain rescaling. Under decay assumptions we establish the full asymptotic expansion in the rescaling parameter of these transforms and provide global estimates for error terms. We show that the resulting asymptotic series is Borel resummable and we provide formulae for the resulting resurgent function, which allows us to give formulae for the Stokes coefficients. A number of classical functions are obtained by applying such meromorphic transforms to elementary functions, of which, the Faddeev quantum dilogarithm, the Euler gamma function, the Riemann zeta function, the Gauss hypergeometric function and the Airy function are excellent examples of our general theory.
