Abstract
We simplify a result by Mangasarian on the existence of solutions to the linear complementarity problem. The simplified condition gives a new geometric interpretation of the result. When used to characterize the matrix classesQ andQ 0, our condition suggests a finitely checkable sufficient condition forP andP 0.
