Superconvergence of the $Q_{k + 1, k}$ - $Q_{k, k + 1}$ divergence-free finite element

Yunqing Huang, Shangyou Zhang

By the standard theory, the stable $Q_{k + 1, k}$ - $Q_{k, k + 1} / Q_{k}^{d c^{'}}$ divergence-free element converges with the optimal order of approximation for the Stokes equations, but only…

On the optimal convergence rate of a Robin-Robin domain decomposition method

Wenbin Chen, Xuejun Xu, Shangyou Zhang

In this work, we solve a long-standing open problem: Is it true that the convergence rate of the Lions' Robin-Robin nonoverlapping domain decomposition(DD) method can be constant,…
