The aim of this volume is two-fold. First, to show how the resurgent methods introduced in volume 1 can be applied efficiently in a non-linear setting; to this
This three-volume work treats divergent series in one variable, especially those arising as solutions to complex ordinary differential or difference equations,
Addressing the question how to “sum” a power series in one variable when it diverges, that is, how to attach to it analytic functions, the volume gives answ
Providing an elementary introduction to analytic continuation and monodromy, the first part of this volume applies these notions to the local and global study o
