When is the space of semi-additive functionals an absolute (neighbourhood) retract?
Pracì Mìžnarodnogo Geometričnogo Centru, 2022 In the present paper proved that if for a given compact Hausdorff space X the hyperspace exp(X) is a contractible compact space then the space OSf(X) is also a contractible compact space.

On r-Compactness in Topological and Bitopological Spaces
Axioms, 2023 This paper defines the so-called pairwise r-compactness in topological and bitopological spaces. In particular, several inferred properties of the r-compact spaces and their connections with other topological and bitopological spaces are studied ...

Thermofield-Bosonization on Compact Space [PDF]
, 2014 We develop the construction of fermionic fields in terms of bosonic ones to describe free and interaction models in the circle, using thermofielddynamics. The description in the case of finite temperature is developed for both normal modes and zero modes.

Locally rich compact sets [PDF]
, 2015 We construct a compact metric space that has any other compact metric space as a tangent, with respect to the Gromov-Hausdorff distance, at all points. Furthermore, we give examples of compact sets in the Euclidean unit cube, that have almost any other ...

Journal of Kufa for Mathematics and Computer, 2011 Using the concept of H-open set, we introduce the concept of H-compact space. Several properties of H-compact spaces are proved , among these are: • H-closed subset of H-compact is     H-compact.

Proceedings of the American Mathematical Society, 1989 A new class of H H -closed spaces, herein referred to as the class of adherent compact spaces, is introduced—and shown to be properly contained in the class of C C -compact spaces. It is also shown, using a construction of Goss and Viglino, that these spaces need not be seminormal.

Locally compact space and continuity
Bibechana, 2010 Topological spaces for being T0, T1, T2 and regular space have been discussed. The conditions for a topological space to be locally compact have also been studied. We have found that a continuous function preserves locally compactness.

On open well-filtered spaces [PDF]
Logical Methods in Computer Science, 2020 We introduce and study a new class of $T_0$ spaces, called open well-filtered spaces. The main results we proved include (1) every well-filtered space is an open well-filtered space; (2) every core-compact open well-filtered space is sober.

مجلة بغداد للعلوم, 2008 The aim of this paper is to introduces and study the concept of CSO-compact space via the notation of simply-open sets as well as to investigate their relationship to some well known classes of topological spaces and give some of his properties.
