Generalized Metric Spaces: Completion, Topology, and Powerdomains via the Yoneda Embedding
Generalized metric spaces are a common generalization of preorders and ordinary metric spaces (Lawvere 1973). Combining Lawvere's (1973) enriched-categorical and Smyth's (1988, 1991) topological view on generalized metric spaces, it is shown ...

La noción de variedad en la clase de espacios de Alexandroff. Superficies cerradas y espacios finitos. [PDF]
Digital topology deals with topological features of 2-D and 3-D digital imagery. Digital images can be represented on a meshed plane or space by means of pixels (2-D) and voxels (3-D), so that they can be managed by using graphs where pixels/voxels are

Adjacency relations induced by some Alexandroff topologies on Zn
Let $ (X, T) $ be an Alexandroff space. We define the adjacency relation $ AR_T $ on $ X $ induced by $ T $ as the irreflexive relation defined for $ x \neq y $ in $ X $ by: $ (x,y) \in AR_T\,\,{\rm{if \;and\; only\; if}}\,\, x \in SN_T(y)\,\,{\rm{or}}\,\, y \in SN_T(x), $ where $ SN_T(z) $ is the smallest open set containing $ z $ in $ (X, T) $ and ...

Topological structuring of the digital plane
We discuss an Alexandroff topology on Z² having the property that its quotient topologies include the Khalimsky and Marcus-Wyse topologies.

On Alexandroff Base Compactifications
In [13] we characterized the completely regular Hausdorff spaces as the class of spaces whose topology is generated by an Alexandrofï base. A space may have more than one Alexandrofï base and each such base determines a Hausdorff compactification .

Topology, calculus and approximation
Presenting basic results of topology, calculus of several variables, and approximation theory which are rarely treated in a single volume, this textbook includes several beautiful, but almost forgotten, classical theorems of Descartes, Erdős, Fejér ...

Elementary concepts of topology
Concise work presents topological concepts in clear, elementary fashion without sacrificing their profundity or exactness. Author proceeds from basics of set-theoretic topology, through topological theorems and questions based on concept of the algebraic

On the Construction of Alexandroff Spaces
Alexandroff spaces, characterized by the property that arbitrary intersections of open sets remain open, play a fundamental role in topology and its applications. This article explores different methods for constructing Alexandroff spaces, organized into
