The second-order $L^2$-flow of inextensible elastic curves with hinged ends in the plane

Chun-Chi Lin, Yang-Kai Lue, Hartmut R. Schwetlick

In the paper published in Duke Math. J. 1993, Y. Wen studied a second-order parabolic equation for inextensible elastic \emph{closed} curves in ${\mathbb{R}}^2$ toward inextensible…
