Semi-Discrete Linear Hyperbolic Curvature flow

James McCoy, Rohan St Hill

We consider evolution of piecewise linear curves with boundary by linear hyperbolic curvature flows. Given appropriate boundary behaviours we find corresponding self-similar soluti…

Length-constrained and length-penalised curve diffusion flows of planar curves inside cones

Mashniah A. Gazwani, James A. McCoy

We study families of smooth, embedded, regular planar curves $α : [- 1, 1] \times [0, T) \to R^{2}$ with generalised Neumann boundary conditions ins…

On the generalised ideal flow of closed planar curves

James McCoy, Glen Wheeler

For each integer $m \geq 0$ we study the $m$ -ideal energy \[ E_m[γ]:=\frac12\int_γk_{s^m}^2\,ds \] on closed immersed planar curves, where $k$ is signed curvature and $s$ is arclength…
