Opis

These are the proceedings of a one-week international conference centered on asymptotic analysis and its applications. They contain major contributions dealing with- mathematical physics: PT symmetry, perturbative quantum field theory, WKB analysis, - local dynamics: parabolic systems, small denominator questions, - new aspects in mould calculus, with related combinatorial Hopf algebras and application to multizeta values, - a new family of resurgent functions related to knot theory.
