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 …

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 …

Generalized power cones: optimal error bounds and automorphisms

Y Lin, SB Lindstrom, BF Lourenço, TK Pong - SIAM Journal on Optimization, 2024 - SIAM
Error bounds are a requisite for trusting or distrusting solutions in an informed way. Until
recently, provable error bounds in the absence of constraint qualifications were unattainable …

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

In this paper, we investigate the structure of Lyapunov-like transformations on the extended
second order cone, considered as a multivariate version of topheavy cone with respect to an …

The Nonconvex Second-Order Cone: Algebraic Structure Toward Optimization

B Alzalg, L Benakkouche - Journal of Optimization Theory and Applications, 2024 - Springer
This paper explores the nonconvex second-order cone as a nonconvex conic extension of

cones. We convert a linear complementarity problem on an extended second order cone …

Primal interior-point decomposition algorithms for two-stage stochastic extended second-order cone programming

B Alzalg - Optimization, 2018 - Taylor & Francis
We study and solve the two-stage stochastic extended second-order cone programming
problem. We show that the barrier recourse functions and the composite barrier functions for …

Isotonicity of the metric projection with respect to the mutually dual orders and complementarity problems

D Kong, L Liu, J Li, Y Wu - Optimization, 2022 - Taylor & Francis
In this paper, as an extension of the isotone projection cone, we consider the isotonicity of
the metric projection operator with respect to the mutually dual orders induced by the cone …
