Electron. J. Differ. Equ. 1996(11), Paper 11, 9 p. (1996)

Summary

Summary: We present an elementary and short proof for regularity of second order elliptic differential equations with homogeneous Dirichlet boundary conditions. The proof uses a discrete function space with piecewise multilinear functions and symmetry techniques on the unit cube.
