題 目：Resurgent theory from the QFT perspective

内容簡介：Resurgent theory was originally developed by French mathematician Jean Ecalle to prove Dulac conjecture about finiteness of limiting cycles in ODEs, and it immediately found applications in quantum mechanics which is now called exact WKB analysis. The theory develops steadily during last three decades with many beautiful algebraic structures unrivaled. Recently, it exerts many activities in quantum field theory and topological string theory. In this talk, I will review the basics of resurgence theory including alien derivatives and transseries, then a typical interplay with gauge theory, namely the Witten-Reshetikhin-Turaev (WRT) invariants in Chern-Simons theory. The talk is partially based on joint works with Li HAN, Yong LI and David SAUZIN.
