North-Holland Publishing Company ON MONOTONICITY IN PARAMETRIC LINEAR COMPLEMENTARITY PROBLEMS
This paper generalizes the answers that were given by R.W. Cottle to questions that were originally raised by G. Maier. Essentially, we give necessary and sufficient conditions for some notions of monotonicity of solutions for the parametric linear complementarity problem. Our proofs are direct ones and not algorithmic, as Cottle's proofs are, and also cover a broader class of matrices. 1
