Rigorous exponential asymptotics and applications to differential systems
Abstract:- The talk focuses on rigorous results in exponential asymptotics of differential systems, using the modern approach of the theory of resummation of (trans)series, explained in this context. We then discuss new techniques derived from these results, for reconstructing differential systems from particular solutions and for understanding the structure of singularities of solutions of nonlinear differential equations.
