• On the Affine Heat Equation for Non-Convex Curves 

      Angenent, Sigurd; Sapiro, Guillermo; Tannenbaum, Allen R. (Georgia Institute of TechnologyAmerican Mathematical Society, 1998-07)
      In this paper, we extend to the non-convex case the affine invariant geometric heat equation studied by Sapiro and Tannenbaum for convex plane curves. We prove that a smooth embedded plane curve will converge to a point ...
