First order least squares method with weakly imposed boundary condition for convection dominated diffusion problems
Huangxin Chen, Guosheng Fu, Jingzhi Li +1
We present and analyze a first order least squares method for convection dominated diffusion problems, which provides robust L2 a priori error estimate for the scalar variable even…

Multilevel Preconditioner with Stable Coarse Grid Corrections for the Helmholtz Equation
Huangxin Chen, Haijun Wu, Xuejun Xu
In this paper we consider a class of robust multilevel precontioners for the Helmholtz equation with high wave number. The key idea in this work is to use the continuous interior p…
