Chern character for totally disconnected groups [PDF]

open access: yes, 2009
In this paper we construct a bivariant Chern character for the equivariant $ KK $-theory of a totally disconnected group with values in bivariant equivariant cohomology in the sense of Baum and Schneider.

Strong Proximal Continuity and Convergence

open access: yesAbstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
In several situations the notion of uniform continuity can be strengthened to strong uniform continuity to produce interesting properties, especially in constrained problems. The same happens in the setting of proximity spaces. While a parallel theory for uniform and strong uniform convergence was recently developed, and a notion of proximal ...

On bornological semigroups [PDF]

open access: yes2015 International Conference on Research and Education in Mathematics (ICREM7), 2015
In this paper we introduce and study the concept of a bornological semigroup. This generalizes the theory of algebraic semigroup from the algebraic setting to the framework of bornological set. Working with bornological set allows to extend the scope of the latter theory considerably.

Caristi Type Coincidence Point Theorem in Topological Spaces

open access: yesJournal of Applied Mathematics, Volume 2013, Issue 1, 2013., 2013
A generalized Caristi type coincidence point theorem and its equivalences in the setting of topological spaces by using a kind of nonmetric type function are obtained. These results are used to establish variational principle and its equivalences in d‐complete spaces, bornological vector space, seven kinds of completed quasi‐semimetric spaces equipped ...

Statistical Convergence in Function Spaces

open access: yesAbstract and Applied Analysis, Volume 2011, Issue 1, 2011., 2011
We study statistical versions of several classical kinds of convergence of sequences of functions between metric spaces (Dini, Arzelà, and Alexandroff) in different function spaces. Also, we discuss a statistical approach to recently introduced notions of strong uniform convergence and exhaustiveness.

An Ascoli theorem for sequential spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 26, Issue 5, Page 303-315, 2001., 2001
Ascoli theorems characterize “precompact” subsets of the set of morphisms between two objects of a category in terms of “equicontinuity” and “pointwise precompactness,” with appropriate definitions of precompactness and equicontinuity in the studied category.

Locally convex structures on higher local fields [PDF]

open access: yes, 2013
We establish how a higher local field can be described as a locally convex vector space once an embedding of a local field into it has been fixed. This extends previous results that had been obtained in the two-dimensional case.

Extensions defined using bornologies

open access: yesApplied General Topology, 2013
Many extensions of a space X such that the remainder Y is closed can be constructed as B-extensions, that is, by defining a topology on the disjoint union X [ Y , provided there exists a map, satisfying some conditions, from a basis of Y into the family ...

Strictly barrelled disks in inductive limits of quasi‐(LB)‐spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 4, Page 727-732, 1996., 1996
A strictly barrelled disk B in a Hausdorff locally convex space E is a disk such that the linear span of B with the topology of the Minkowski functional of B is a strictly barrelled space. Valdivia′s closed graph theorems are used to show that closed strictly barrelled disk in a quasi‐(LB)‐space is bounded. It is shown that a locally strictly barrelled

Some remarks about Mackey convergence

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 4, Page 659-664, 1995., 1994
In this paper, we examine Mackey convergence with respect to K‐convergence and bornological (Hausdorff locally convex) spaces. In particular, we prove that: Mackey convergence and local completeness imply property K; there are spaces having K‐ convergent sequences that are not Mackey convergent; there exists a space satisfying the Mackey convergence ...
