Abstract

In this article, we study the evolution of open inextensible planar curves with hinged ends. We obtain long time existence of C^∞-smooth solutions during the evolution, given the initial curves that are only C²-smooth with vanishing curvature at the boundary. Moreover, the asymptotic limits of this flow are inextensible elasticae. Our method and result extend the work by Wen (Duke Math. J. 70(3):683–698, 1993).
