The Continuity of Subdifferential Mapping

open access: yesJournal of Mathematical Analysis and Applications, 1997
The authors discuss continuity of the subdifferential mapping of the gauge of a bounded convex set with the origin an interior point and find a single-valuedness criterion for the mapping.

Best Proximity Pairs Theorems for Continuous Set-Valued Maps

open access: yesFixed Point Theory and Applications, 2008
A best proximity pair for a set-valued map F:A⊸B with respect to a set-valued map G:A⊸A is defined, and a new existence theorem of best proximity pairs for continuous set-valued maps is proved in nonexpansive retract metric spaces.

Hyperspaces of Superparacompact Spaces and Continuous Maps

open access: yesUniversal Journal of Mathematics and Applications, 2019
In the present paper we establish that the space $\exp_\beta X$ of compact subsets of a Tychonoff space $X$ is superparacompact iff $X$ is so.

Red and blue states: dichotomized maps mislead and reduce perceived voting influence

open access: yesCognitive Research, 2023
In the United States the color red has come to represent the Republican party, and blue the Democratic party, in maps of voting patterns. Here we test the hypothesis that voting maps dichotomized into red and blue states leads people to overestimate ...

On Perturbations of Continuous Maps [PDF]

open access: yesCanadian Mathematical Bulletin, 2013
AbstractWe give sufficient conditions for the following problem: given a topological space X, ametric space Y, a subspace Z of Y, and a continuous map f from X to Y, is it possible, by applying to f an arbitrarily small perturbation, to ensure that f(X) does not meet Z?

An Efficient Algorithm for Zeros of Bounded Generalized Ghi-Quasi-Accretive Maps

open access: yesThe Proceedings of the Nigerian Academy of Science, 2013
This is a research announcement of the following result. Let E be a real normed linear space in which the single-valued normalized duality map is Holder continuous on balls and let A: E → E be a bounded generalized Φ-quasi-accretive map.

The class of simple dynamics systems

open access: yesApplied General Topology, 2020
In this paper, we study the class of simple dynamical systems on R induced by continuous maps having finitely many non-ordinary points. We characterize this class using labeled digraphs and dynamically independent sets.

On weakly continuous mappings [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
P. E. Long and D. A. Carnahan studied several properties of almost continuous mappings in the sense of Singal (denoted by a.c.S.) in Proc. Amer. Math. Soc. 38 (1973), 413-418. In this note, it is shown that “a.c.S.” in some theorems of the above paper can be replaced by “weakly continuous".

On extension of pairwise θ-continuous maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
The aim of the paper is to find suitable conditions so as to ultimately establish the existence and uniqueness of the extension of a pairwise θ-continuous map onto an arbitrary extension-space of a bitopological space.

Extending continuous maps [PDF]

open access: yesProceedings of the forty-fifth annual ACM symposium on Theory of Computing, 2013
We consider several basic problems of algebraic topology, with connections to combinatorial and geometric questions, from the point of view of computational complexity.The extension problem asks, given topological spaces X,Y, a subspace A ⊆ X, and a (continuous) map f:A -> Y, whether f can be extended to a map X -> Y.
