Existence and stability results based on asymptotic analysis for semidefinite linear complementarity problems

This work is devoted to the study of existence and stability results of semidefinite linear complementarity problems (SDLCP). Our approach consists of approximating the variational inequality formulation of the SDLCP by a sequence of suitable chosen variational inequalities. This provides particular estimates for the asymptotic cone of the solution set of the SDLCP. We thus … Read more

Linear complementarity problems over symmetric cones: Characterization of Qb-transformations and existence results

This paper is devoted to the study of the {symmetric cone linear complementarity problem} (SCLCP). In this context, our aim is to characterize the class Q_b in terms of larger classes, such as Q and R_0. For this, we introduce the class F and García’s transformations. We studied them for concrete particular instances (such as … Read more
