Superconvergent quadriatic finite element on uniform tetrahedral meshes

Yunqing Huang, Shangyou Zhang

By a direct computation, we show that the interpolation of a function is also a local -projection on uniform tetrahedral meshes, i.e., the difference is -orth…

Convergent finite elements on arbitrary meshes, the WG method

Ran Zhang, Shangyou Zhang

On meshes with the maximum angle condition violated, the standard conforming, nonconforming, and discontinuous Galerkin finite elements do not converge to the true solution when th…
