Structure and classification results for the -elastica problem
arXiv:1908.01569 · doi:10.1353/ajm.2022.0030
Abstract
Consider the following variational problem: among all curves in of fixed length with prescribed end points and prescribed tangents at the end points, minimise the -norm of the curvature. We show that the solutions of this problem, and of a generalised version, are characterised by a system of differential equations. Furthermore, we have a lot of information about the structure of solutions, which allows a classification.
