An optimal two-side Robin-Robin domain decomposition method for H(div)-elliptic problem
Na Xuyang
In this paper, we develop a new two-side Robin-Robin domain decomposition method for H(div)-elliptic problem. Numerical results show that the convergence rate of the new algorithm…

Domain Decomposition Methods for Elliptic Problems with High Contrast Coefficients Revisited
Xuyang Na, Xuejun Xu
In this paper, we revisit the nonoverlapping domain decomposition methods for solving elliptic problems with high contrast coefficients. Some interesting results are discovered. We…
