The aim of the present article is to generalize several results of 19 for product spaces X × V, where X is a complete metric space and V is a Banach space and to give considerably simplified proofs. Moreover, we discuss sufficient conditions for the decisive assumptions as well as an application to vector optimization problems.

Hamel, AH; Löhne, A (YOKOHAMA PUBL, 2006)We present two existence principles for minimal points of subsets of the product space X × 2Y, where X stands for a separated uniform space and Y a topological vector space. The two principles are distinct with respect to ...
Lakkis O; Pryer T (2011)We propose a numerical method to approximate the solution of second order elliptic problems in nonvariational form. The method is of Galerkin type using conforming finite elements and applied directly to the nonvariational ...
A framework of forecasting techniques as a checklist to minimize the likelihood of product design failures Borgianni Y (European TRIZ Association, 2017)TRIZ is intended to support, among the others, the forecasting of future versions of technical systems. In this sense, the Laws of Evolution of Technical Systems range among the most powerful methods to predict possible ...
