On properties of some matrix splittings

Henryk A. Jedrzejec and Zbigniew I. Woznicki
 
Properties of some splittings of a monotone matrix A are 
discussed. These properties are fundamental hypotheses in 
the proofs of comparison theorems. This fact is illustrated 
by several results given in the literature.
