Lipschitz upper semicontinuity of linear inequality systems under full perturbations
Jesús Camacho, María Josefa Cánovas, Helmut Gfrerer +1
The present paper is focused on the computation of the Lipschitz upper semicontinuity modulus of the feasible set mapping in the context of fully perturbed linear inequality system…
Feasibility problems via paramonotone operators in a convex setting
J. Camacho, M. J. Cánovas, J. E. Martínez-Legaz +1
This paper is focused on some properties of paramonotone operators on Banach spaces and their application to certain feasibility problems for convex sets in a Hilbert space and con…
Hoffman constant of the argmin mapping in linear optimization
J. Camacho, M. J. Cánovas, H. Gfrerer +1
The main goal of this paper is to provide a point-based expression for the Hoffman constant of the argmin mapping in linear optimization, understood as the sharp Lipschitz constant…
From calmness to Hoffman constants for linear semi-infinite inequality systems
Jesús Camacho, María Josefa Cánovas, Juan Parra
In this paper we focus on different -- global, semi-local and local -- versions of Hoffman type inequalities expressed in a variational form. In a first stage our analysis is devel…
