We give estimates for the convolution product of an arbitrary number of endlessly continuable functions. This allows us to deal with nonlinear operations for the corresponding resurgent series, e.g. substitution into a convergent power…
Fracture functions and their evolution equations are reviewed. Some phenomenological applications are briefly discussed.
