Least-Squares Methods with Nonconforming Finite Elements for General Second-Order Elliptic Equations
Yuxiang Liang, Shun Zhang
In this paper, we study least-squares finite element methods (LSFEM) for general second-order elliptic equations with nonconforming finite element approximations. The equation may…

Several Proofs of Coerciveness of First-Order System Least-Squares Methods for General Second-Order Elliptic PDEs
Shun Zhang
In this paper, we present proofs of the coerciveness of first-order system least-squares methods for general (possibly indefinite) second-order linear elliptic PDEs under a minimal…
