Predictor-corrector, BGN-based parametric finite element methods for surface diffusion
Wei Jiang, Chunmei Su, Ganghui Zhang +1
We present a novel parametric finite element approach for simulating the surface diffusion of curves and surfaces. Our core strategy incorporates a predictor-corrector time-steppin…

Structure-preserving parametric finite element method for curve diffusion based on Lagrange multiplier approaches
Harald Garcke, Wei Jiang, Chunmei Su +1
We propose a novel formulation for parametric finite element methods to simulate surface diffusion of closed curves, which is also called as the curve diffusion. Several high-order…

A semi-discrete first-order low regularity exponential integrator for the "good" Boussinesq equation without loss of regularity
Hang Li, Chunmei Su
In this paper, we propose a semi-discrete first-order low regularity exponential-type integrator (LREI) for the ``good" Boussinesq equation. It is shown that the method is converge…
