Wonderful compactifications of Bruhat-Tits buildings [PDF]
Given a split semisimple group over a local field, we consider the maximal Satake-Berkovich compactification of the corresponding Euclidean building. We prove that it can be equivariantly identified with the compactification which we get by embedding the

End compactifications and general compactifications
Summary: We use the insights of Robinson's nonstandard analysis as a powerful tool to extend and simplify the construction of compactifications of regular spaces. In particular, we deal with the Stone- Čech compactification and compactifications formed from topological ends. For the nonstandard extension of a metric space, the monad of a standard point

The Smirnov compactification as a quotient space of the Stone-Čech compactification
For a separated proximity space, a decomposition of the Stone-Čech compactification is presented which produces the Smirnov compactification and its basic properties by elementary arguments without recourse to clusters or totally bounded uniformities.

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

Exceptional flux compactifications [PDF]
AbstractWe consider type II (non-)geometric flux backgrounds in the absence of brane sources, and construct their explicit embedding into maximal gaugedD= 4 supergravity. This enables one to investigate the critical points, mass spectra and gauge groups of such backgrounds.

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

Measure‐valued processes for energy markets
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 ...

The real spectrum compactification of character varieties: characterizations and applications
We announce results on a compactification of general character varieties that has good topological properties and give various interpretations of its ideal points.

In a fundamental paper [Comment. Math. Helv. 48, 436--491 (1973; Zbl 0274.22011)] \textit{A. Borel} and \textit{J. P. Serre} constructed a compactification of the locally symmetric space \(\Gamma\setminus X\); where \(\Gamma\) is an arithmetic subgroup of the group \(G\) of isometries of a symmetric space \(X\) with nonpositive sectional curvatures ...
