Minimum Action Curves in Degenerate Finsler Metrics Existence and Pr

Presenting a study of geometric action functionals (i.e., non-negative functionals on the space of unparameterized oriented rectifiable curves), this monograph focuses on the subclass of those functionals whose local action is a degenerate type

Preface

This research monograph is an analytical treatment of a geometric problem that recently arose in an applied community [6, 7, 10] focused on developing numerical methods for understanding the pathways of rare transition events in stochastic dynamical systems with small noise. For years, it had been a reoccurring problem that the underlying mathematical framework, Wentzell-Freidlin theory [8], is typically formulated in terms of time-parameterized paths,
