Approximations of Stone–Cech compactifications by Higson compactifications [PDF]

Colloquium Mathematicum, 2001
Let \(X\) be a locally compact metric space with \(d\) a proper metric on \(X\) inducing its topology. The Higson compactification of \(X\) depends on the metric \(d\). This compactification depends on the metric \(d\), but is non-metrizable and has many properties in common with the Stone-Čech compactification.

On the embedding of the Ω-saturation of a topological space

Журнал Белорусского государственного университета: Математика, информатика, 2022
The countably-compactification of a topological space X is such its extension Y, that Y is a completely regular and countably-compact space, and any closed countably-compact subset of X is closed in Y. But this extension does not always exist.

Flux compactification

Reviews of Modern Physics, 2007
We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics.

S-Metrizability and the Wallman basis of a frame [PDF]

Categories and General Algebraic Structures with Applications
The Wallman basis of a frame and the corresponding induced compactification was first investigated by Baboolal [2]. In this paper, we provide an intrinsic characterisation of S-metrizability in terms of the Wallman basis of a frame. Particularly, we show

Toroidal compactifications and Borel-Serre compactifications

Proceedings of the Japan Academy, Series A, Mathematical Sciences
We discuss connections of toroidal compactifications and Borel--Serre compactifications in view of the fundamental diagram of extended period domains. We give a complement to a work of Goresky--Tai.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

Compactification of a convergence space

, 1979
A characterization for the class of convergence spaces having the largest Hausdorff compactification is given, and regularity and λ \lambda -Hausdorffness of modified Richardson compactification are discussed.

Fan-Gottesman Compactification and Scattered Spaces

, 2020
Compactification is the process or result of making a topological space into a compact space. An embedding of a topological space X as a dense subset of a compact space is called a compactification of X. There are a lot of compactification methods but we

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...
