An algorithm for mean curvature motion. (English) Zbl 1061.35147
Author’s abstract: We propose in this paper a new algorithm for computing the evolution by mean curvature of a hypersurface. Our algorithm is a variant of the variational approach of F. Almgren, J. E. Taylor and L.-H. Wang [SIAM J. Control Optim. 31, No. 2, 387–438 (1993; Zbl 0783.35002)]. We show that it approximates, as the time-step goes to zero, the generalized motion (in the sense of barriers or viscosity solutions). The results still hold for the anisotropic mean curvature motion, as long as the anisotropy is smooth.
