$ W^{1, \infty} $-seminorm superconvergence of the block finite element method for the five-dimensional Poisson equation

This study focused on the superconvergence of the finite element method for the five-dimensional Poisson equation in the $ W^{1, \infty} $-seminorm. Specifically, we investigated the block finite element method, which is a tensor-product finite element approach applied to regular rectangular partiti...
