New perturbation results for solving the linear complementarity problem with Po-matrices Original Research Article

We provide new conditions under which the linear complementarity problem (LCP) can be solved by a perturbation method when the associated matrix is a Po-matrix. The new conditions apply to both degenerate and nondegenerate LCPs. Moreover, these conditions do not require that the Po-matrix belong to another matrix class such as, for example, the Ro-matrix class.
