Extended Lorentz cones and variational inequalities on cylinders

SZ Németh, G Zhang - Journal of optimization Theory and Applications, 2016 - Springer
Solutions of a variational inequality problem defined by a closed and convex set and a
mapping are found by imposing conditions for the monotone convergence with respect to a …

How to project onto extended second order cones

OP Ferreira, SZ Németh - Journal of Global optimization, 2018 - Springer
The extended second order cones were introduced by Németh and Zhang (J Optim Theory
Appl 168 (3): 756–768, 2016) for solving mixed complementarity problems and variational …

Isotonicity of the metric projection by Lorentz cone and variational inequalities

D Kong, L Liu, Y Wu - Journal of Optimization Theory and Applications, 2017 - Springer
In this paper, we first discuss the geometric properties of the Lorentz cone and the extended
Lorentz cone. The self-duality and orthogonality of the Lorentz cone are obtained in Hilbert …

Notes on the optimization problems corresponding to polynomial complementarity problems

VT Hieu, Y Wei, JC Yao - Journal of Optimization Theory and Applications, 2020 - Springer
This work is motivated by a conjecture of Che et al.(J Optim Theory Appl 168: 475–487,
2016) which says that if the feasible region of a tensor complementarity problem is …

Variational inequalities over the cone of semidefinite positive symmetric matrices and over the Lorentz cone

A Auslender - Optimization methods and software, 2003 - Taylor & Francis
A systematic way for generating penalty and barrier methods is proposed in order to solve
variational inequalities with a maximal monotone map and over a feasible set which is the …

The monotone extended second-order cone and mixed complementarity problems

Y Gao, SZ Németh, R Sznajder - Journal of Optimization Theory and …, 2022 - Springer
In this paper, we study a new generalization of the Lorentz cone L^ n_+ L+ n, called the
monotone extended second-order cone (MESOC). We investigate basic properties of …

Extended Lorentz cones and mixed complementarity problems

SZ Németh, G Zhang - Journal of Global optimization, 2015 - Springer
In this paper we extend the notion of a Lorentz cone in a Euclidean space as follows: we
divide the index set corresponding to the coordinates of points in two disjoint classes. By …

Generalized polynomial complementarity problems over a polyhedral cone

T Shang, J Yang, G Tang - Journal of Optimization Theory and Applications, 2022 - Springer
The goal of this paper is to investigate a new model, called generalized polynomial
complementarity problems over a polyhedral cone and denoted by GPCPs, which is a …

Penalized complementarity functions on symmetric cones

S Kum, Y Lim - Journal of Global optimization, 2010 - Springer
We show that penalized functions of the Fischer–Burmeister and the natural residual
functions defined on symmetric cones are complementarity functions. Boundedness of the …
