On maps: continuous, closed, perfect, and with closed graph [PDF]
International Journal of Mathematics and Mathematical Sciences, 1997 This paper gives relationships between continuous maps, closed maps, perfect maps, and maps with closed graph in certain classes of topological spaces.

Uniformly continuous maps between ends of R-trees [PDF]
, 2009 There is a well-known correspondence between infinite trees and ultrametric spaces which can be interpreted as an equivalence of categories and comes from considering the end space of the tree.

Some New Structures in Neutrosophic Metric Spaces [PDF]
Neutrosophic Sets and Systems, 2021 Neutrosophic sets deals with inconsistent, indeterminate and imprecise datas. The concept of Neutrosophic Metric Space (NMS) uses the idea of continuous t- norm and continuous t - conorm in intuitionistic fuzzy metric spaces.

Extendability of Continuous Maps Is Undecidable [PDF]
Discrete & Computational Geometry, 2013 We consider two basic problems of algebraic topology, the extension problem and the computation of higher homotopy groups, from the point of view of computability and computational complexity. The extension problem is the following: Given topological spaces X and Y, a subspace A\subseteq X, and a (continuous) map f:A->Y, decide whether f can be ...

Uniqueness of equilibrium measures for countable Markov shifts and multidimensional piecewise expanding maps [PDF]
, 2003 We prove that potentials with summable variations on topologically transitive countable Markov shifts have at most one equilibrium measure.

Best Proximity Pairs Theorems for Continuous Set-Valued Maps
Fixed 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
Universal 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
Cognitive 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 ...

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