A preconditioned boundary value method for advection-diffusion equations with half Laplacian via spectrum doubling
Pu Yuan, Paul Zegeling, Xian-Ming Gu
In this paper, we study an evolution equation that involves a half-Laplacian operator derived from the Riesz fractional Laplacian, combined with a differential operator \(\mathcal{…

Simulation of thin film flows with a moving mesh mixed finite element method
Hong Zhang, Paul A Zegeling
We present an efficient mixed finite element method to solve the fourth-order thin film flow equations using moving mesh refinement. The moving mesh strategy is based on harmonic m…
