Continuous and discrete maximum/minimum principles for a class of boundary-value problems of elliptic type with Neumann boundary conditions are treated. The main results in this work are related to discrete versions of the maximum/minimum principles. The authors obtain practical conditions on schemes used in the finite element method (FEM) and finite difference method (FDM). The paper opens perspectives for extensions of the results obtained to $$hp$$-versions of FEM and to more general elliptic problems.
