Metrization theorems concerning relative compactness [PDF]
, 1979 Many of earlier and recent results obtained for p-spaces and their relatives can be extended by using a simple and natural concept (relative compactness) which was defined and investigated in an earlier paper of the author.In the present paper extensions

The local triangle axiom in topology and domain theory
Applied General Topology, 2013 We introduce a general notion of distance in weakly separated topological spaces. Our approach differs from existing ones since we do not assume the reflexivity axiom in general.

A Rim-Metrizable Continuum [PDF]
Proceedings of the American Mathematical Society, 1995 A locally connected rim-metrizable continuum is constructed which admits a continuous mapping onto a non rim-metrizable space.

The Smirnov- and Bing-Nagata-Smirnov Metrization Theorems
, 2020 In this essay we give a sufficient background to, and prove, the classical Bing-Nagata-Smirnov metrization theorem. Thus we show that a topological space is metrizable if, and only if, it is regular and has a countably locally finite basis.

Applied General Topology, 2018 In [1], A. A. Borubaev introduced the concept of τ-metric space, where τ is an arbitrary cardinal number. The class of τ-metric spaces as τ runs through the cardinal numbers contains all ordinary metric spaces (for τ = 1) and thus these spaces are a ...

On Frink's type metrization of weighted graphs [PDF]
, 2021 Using the technique of the metrization theorem of uniformities with countable bases, in this note we provide, test and compare an explicit algorithm to produce a metric d(x,y) between the vertices x and y of an affinity weighted undirected graph.Fil ...

Karpatsʹkì Matematičnì Publìkacìï, 2018 The idempotent mathematics is a part of mathematics in which arithmetic operations in the reals are replaced by idempotent operations. In the idempotent mathematics, the notion of idempotent measure (Maslov measure) is a counterpart of the notion of ...

Barbilian's metrization procedure in the plane yields either Riemannian or Lagrange generalized metrics [PDF]
, 1996 summary:In the present paper we answer two questions raised by Barbilian in 1960. First, we study how far can the hypothesis of Barbilian's metrization procedure can be relaxed. Then, we prove that Barbilian's metrization procedure in the plane generates

Advanced Science, EarlyView.Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in
