Projective algorithms for solving complementarity problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 2, Page 99-113, 2002., 2002
We present robust projective algorithms of the von Neumann type for the linear complementarity problem and for the generalized linear complementarity problem. The methods, an extension of Projections Onto Convex Sets (POCS) are applied to a class of problems consisting of finding the intersection of closed nonconvex sets. We give conditions under which

A primal-dual approach of weak vector equilibrium problems

open access: yesOpen Mathematics, 2018
In this paper we provide some new sufficient conditions that ensure the existence of the solution of a weak vector equilibrium problem in Hausdorff topological vector spaces ordered by a cone.

Generalized strongly set‐valued nonlinear complementarity problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 3, Page 597-604, 1999., 1999
In this paper, we introduce a new class of generalized strongly set‐valued nonlinear complementarity problems and construct new iterative algorithms. We show the existence of solutions for this kind of nonlinear complementarity problems and the convergence of iterative sequences generated by the algorithm. Our results extend some recent results in this

On the spherical convexity of quadratic functions [PDF]

open access: yes, 2018
In this paper we study the spherical convexity of quadratic functions on spherically convex sets. In particular, conditions characterizing the spherical convexity of quadratic functions on spherical convex sets associated to the positive orthants and ...

Counting Unique-Sink Orientations [PDF]

open access: yes, 2013
Unique-sink orientations (USOs) are an abstract class of orientations of the n-cube graph. We consider some classes of USOs that are of interest in connection with the linear complementarity problem.

Combinatorial Characterizations of K-matrices [PDF]

open access: yes, 2010
We present a number of combinatorial characterizations of K-matrices. This extends a theorem of Fiedler and Ptak on linear-algebraic characterizations of K-matrices to the setting of oriented matroids.

New error bounds for linear complementarity problems of weakly chained diagonally dominant B-matrices

open access: yesOpen Mathematics, 2017
Some new error bounds for the linear complementarity problems are obtained when the involved matrices are weakly chained diagonally dominant B-matrices. Numerical examples are given to show the effectiveness of the proposed bounds.

Interior-point methods for P∗(κ)-linear complementarity problem based on generalized trigonometric barrier function

open access: yes, 2017
Recently, M. Bouafoa, et al. [3] investigated a new kernel function which differs from the self-regular kernel functions. The kernel function has a trigonometric Barrier Term. In this paper we generalize the analysis presented in the above paper for P∗(κ)

A self adaptive inertial subgradient extragradient algorithm for variational inequality and common fixed point of multivalued mappings in Hilbert spaces

open access: yesDemonstratio Mathematica, 2019
We consider a new subgradient extragradient iterative algorithm with inertial extrapolation for approximating a common solution of variational inequality problems and fixed point problems of a multivalued demicontractive mapping in a real Hilbert space ...
