Title: Resurgence, Phase Transitions & Extrapolation

Abstract: There are several important conceptual and computational questions in quantum field theory which have recently been approached from a new perspective motivated by “resurgent asymptotics”, which is a novel mathematical formalism that seeks to unify perturbative and non-perturbative physics. I will review the basic ideas behind the connections between resurgent asymptotics and physics, and report on some current applications to quantum field theory and phase transitions, and new ore powerful methods of extrapolation between physically interesting parametric regimes.
