Alexandroff duplicate and βκ [PDF]
We discuss spaces and the Alexandroff duplicates of those spaces that admit a Č-S embedding into the Čech-Stone compactification of a discrete space.

The Alexandroff Duplicate and its subspaces [PDF]
We study some topological properties of the class of the Alexandroff duplicates and their subspaces. We give a characterization of metrizability and Lindel¨of properties of subspaces of the Alexandroff duplicate.

Uniformizable functional Alexandroff spaces
In the following text we show that the Alexandroff space $X$ is uniformizable if and only if the collection of all smallest neighbourhoods is a partition of $X$. Moreover the Alexandroff space $X$ is uniformizable and functional Alexandroff ($k-$primal) if and only if the collection of all smallest neighbourhoods is a partition of $X$ into its finite ...

On the triviality of flows in Alexandroff spaces [PDF]
We prove that the unique possible flow in an Alexandroff T0-space is the trivial one. On the way of motivation, we relate Alexandroff spaces with topological hyperspaces.

The Alexandroff property and the preservation of strong uniform continuity [PDF]
In this paper we extend the theory of strong uniform continuity and strong uniform convergence, developed in the setting of metric spaces in, to the uniform space setting, where again the notion of shields plays a key role.

Statistical Convergence in Function Spaces [PDF]
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.

On some non-Archimedean spaces of Alexandroff and Urysohn
In [Math. Ann. 98, 89-106 (1927; JFM 53.0559.01)] Alexandroff and Urysohn provided characterizations of the spaces \({}^\omega\omega\) (the irrationals), its subspace \(\bigcup_{n\in\omega}^\omega n\) and the complement of a point in the Cantor set -- these characterizations were in the spirit of \textit{L.

Necessary or sufficient condition for Alexandroff topological spaces to be cordial graphic
In this paper, we explore the property of being a cordial graphic and establish that it corresponds to an Alexandroff topological space. We analyze how the characteristics of cordial graphs align with the principles of Alexandroff topology and provide ...

The Centre of the Spaces of Banach Lattice-Valued Continuous Functions on the Generalized Alexandroff Duplicate [PDF]
We characterize the centre of the Banach lattice of Banach lattice 𝐸-valued continuous functions on the Alexandroff duplicate of a compact Hausdorff space 𝐾 in terms of the centre of 𝐶(𝐾,𝐸), the space of 𝐸-valued continuous functions on 𝐾.
