title = "Recovery based finite difference scheme on unstructured mesh",
abstract = "In the article, we propose a systematic method to generate finite difference scheme on unstructured mesh. Our method is based on recovery technique in the finite element community. The computed solutions own the same superconvergence (or ultraconvergence) property as recovered gradient and Hessian.",
