Abstract: A subset A of a locally convex space E is called (relatively) sequentially complete if every Cauchy sequence {xn}n=1∞ in E contained in A converges to a point x∈ A (a point x∈ E). […]

Abstract: If T is a (densely defined) self-adjoint operator acting on a complex Hilbert space H and I stands for the identity operator, we introduce the delta function operator λ {mapping} δ (λI – T) at T. When T is a bounded operator, then δ […]

Abstract: This paper analyzes the Lipschitz behavior of the feasible set mapping associated with linear and convex inequality systems in Rn. To start with, we deal […]

Carlos Argáez (Faculty of Physical Sciences, University of Iceland), María Josefa Cánovas, Juan Parra (University Miguel Hernández of Elche) 
Abstract: We are concerned with finite linear constraint systems in a parametric framework where the right-hand side is an affine function of the perturbation parameter. Such structured perturbations provide a unified framework for different parametric models in […]

Abstract: This paper generalizes and unifies different recent results as well as provides a new methodology concerning vector optimization problems involving composite mappings in locally convex Hausdorff topological vector spaces. The Lagrangian […]
