Super-approximation and optimal convergence of the stabilized BGN method with piecewise linear parametric finite elements for curve-shortening flow
Genming Bai
We develop a bihomotopy argument to estimate the discrete material time derivatives of consistency functionals. Combined with summation-by-parts, this argument yields a directional…

Stabilization and optimal convergence of Dziuk's method with piecewise linear parametric finite elements for curve-shortening flow
Genming Bai
We propose a stabilized version of the fully discrete Dziuk's method for the curve-shortening flow of a closed planar curve with piecewise linear parametric finite elements. With a…
