The term "resurgent function" refers to a concept in the field of mathematics, particularly in relation to the study of analytic functions and their asymptotic behavior. Resurgence is a technique that arises in the context of the study of divergent series and the behavior of functions near singularities. In simpler terms, resurgence can be thought of as a method to make sense of divergent series by relating them to certain "resurgent" functions that capture their asymptotic behavior.
