A first order system least squares method for the Helmholtz equation
Huangxin Chen, Weifeng Qiu
We present a first order system least squares (FOSLS) method for the Helmholtz equation at high wave number k, which always deduces Hermitian positive definite algebraic system. By…

Robust a Posteriori Error Estimates for HDG method for Convection-Diffusion Equations
Huangxin Chen, Jingzhi Li, Weifeng Qiu
We propose a robust a posteriori error estimator for the hybridizable discontinuous Galerkin (HDG) method for convection-diffusion equations with dominant convection. The reliabili…
