A characterization of singular endomorphisms of a barrelled Pták space by Damir Franekić

“…The concept of topological divisor of zero has been extended to endomorphisms of a locally convex topological vector space (LCTVS). A characterization of singular endomorphisms, similar to that of Yood [1], is obtained for endomorphisms of a barrelled Pták (fully complete) space and it is shown that each such endomorphism is a topological divisor of zero. …”

A Survey of Cognitive Radio Access to TV White Spaces by Maziar Nekovee

“…Cognitive radio is being intensively researched as the enabling technology for license-exempt access to the so-called TV White Spaces (TVWS), large portions of spectrum in the UHF/VHF bands which become available on a geographical basis after digital switchover. …”

Functional-Type Caristi–Kirk Theorem on Menger Space and Application by Soumia Chaira, Mohammed Dahmouni, Abderrahim Eladraoui, Mustapha Kabil

“…In this paper, we extend Caristi’s fixed point theorem in metric spaces to probabilistic metric spaces, and also, we prove some common fixed point theorems for a pair of mappings satisfying a system of Caristi-type contractions in the setting of a Menger space. …”

Design and sensory quality. Materials and performance for communication in museum spaces by Teresa Villani

“…Design can provide the means to guide perceptive processes, by trying to act on the environment’s ability to provide intelligible and meaningful information. Making a space communicative by enhancing its usability entails anticipating perceptive processes and pursuing better quality for human-environment interaction. …”

Some Common Fixed Point Theorems in Partial Metric Spaces by Erdal Karapınar, Uğur Yüksel

“…Many problems in pure and applied mathematics reduce to a problem of common fixed point of some self-mapping operators which are defined on metric spaces. One of the generalizations of metric spaces is the partial metric space in which self-distance of points need not to be zero but the property of symmetric and modified version of triangle inequality is satisfied. …”

Convex Sweeping Processes with Noncompact Perturbations and with Delay in Banach Spaces by A. G. Ibrahim, F. Aladsani

“…We prove two results concerning the existence of solutions for functional differential inclusions that are governed by sweeping processes, with noncompact valued perturbations in Banach spaces. Indeed, we have two goals. The first is to give a technique that allows considering sweeping processes with noncompact valued perturbations and associated with a multivalued function depending on time. …”
