On Weakening Conditions for Discrete Maximum Principles for Linear Finite Element Schemes.
In this work we discuss weakening requirements on the set of sufficient conditions due to Ph. Ciarlet [4,5] for matrices associated to linear finite element schemes, which is commonly used for proving validity of discrete maximum principles (DMPs) for the second order elliptic problems. © Springer-Verlag Berlin Heidelberg 2009
