Error bounds for mixed set-valued vector inverse quasi-variational inequalities
Journal of Inequalities and Applications, 2020 The purpose of this paper is to introduce and study the mixed set-valued vector inverse quasi-variational inequality problems (MSVIQVIPs) and to obtain error bounds for this kind of MSVIQVIP in terms of the residual gap function, the regularized gap ...

Gap functions for vector variational inequalities [PDF]
, 2015 In this article, we intend to study several scalar-valued gap functions for Stampacchia and Minty-type vector variational inequalities. We first introduce gap functions based on a scalarization technique and then develop a gap function without any ...

Exploiting Higher-order Derivates in Convex Optimization Methods [PDF]
, 2023 Exploiting higher-order derivatives in convex optimization is known at least since 1970's. In each iteration higher-order (also called tensor) methods minimize a regularized Taylor expansion of the objective function, which leads to faster convergence ...

Optical conductivity, Drude weight and plasmons in twisted graphene bilayers
New Journal of Physics, 2013 We numerically calculate the optical conductivity of twisted graphene bilayers within the continuum model. To obtain the imaginary part, we employ the regularized Kramers–Kronig relation, allowing us to discuss arbitrary twist angles, chemical potential ...

Solving non-monotone equilibrium problems via a DIRECT-type approach [PDF]
, 2021 A global optimization approach for solving non-monotone equilibrium problems (EPs) is proposed. The class of (regularized) gap functions is used to reformulate any EP as a constrained global optimization program and some bounds on the Lipschitz constant ...
