It is known that perturbative series in quantum field theory is typically non-convergent. While there is a standard way to resum non-convergent series called Borel resummation, it is supposed that naive Borel resummation does not work in many field theories such as QCD . Resurgence theory is often used to rescue this type of situation both in physics and mathematics while we do not know yet it works in which class of field theories. In this talk, I will discuss how resummation of perturbative series is related to exact results in supersymmetric gauge theories.
