Discrete maximum principle for Poisson equation with mixed boundary conditions solved by hp-FEM
We present a proof of the discrete maximum principle (DMP) for the 1D Poisson equation equipped with mixed Dirichlet-Neumann boundary conditions. The problem is discretized using finite elements of arbitrary length...

On favorable bounds on the spectrum of discretized Steklov-Poincaré operator and applications to domain decomposition methods in 2D
properties of the discretization methods and the conditioning of the resulting linear systems. If applicable, the boundary element methods typically provide better to assume that the matrices corresponding to the same fine...

On discrete maximum principles for nonlinear elliptic problems
We give a short review of the most important results devoted to discrete counterparts of the maximum principle (called discrete maximum principles, DMPs), mainly in the framework of the finite element method, and also prese...

On discrete maximum principle for tetrahedral elements satisfying a weakened acute type condition.
We prove that a discrete maximum principle holds for continuous piecewise linear finite element approximations for the Poisson equation with the Dirichlet boundary conditions also under a condition of the existence of some ...
