Topological and Nonstandard Extensions

Monatshefte f�r Mathematik, 2004
The authors describe a general topological framework that encompasses both the Stone-Čech compactification of a discrete space \(X\) and the ``nonstandard extensions'' of \(X\), in the sense of nonstandard analysis. The basic notion is that of topological extension of a set \(X\), consisting of two ingredients; (i) a \({\mathbf T}_i\) space \(X ...

On Two Questions About Topological (and Nonstandard) Extensions

Monatshefte für Mathematik, 2006
A topological extension of a set \(X\) with the discrete topology is defined in this paper to be a \(T_1\) topological space \({}^*X\) containing \(X\), such that every function \(f: X \to X\) extends to a continuous function \({}^*f : {}^*X \to {}^*X\) in such a way that (1) \({}^*\) is a functor, i.e., \({}^*g \circ {}^*f = {}^*(g \circ f)\) for all \

Stability Concepts in Topological Dynamics by Nonstandard Methods

Acta Applicandae Mathematica, 1997
Motivated by, and using, methods of nonstandard analysis, the paper introduces four topologically-defined concepts of stability of a continuous semiflow on a compact subset \(K\) of \(R^{n}\). Standard versions of the results are also presented. Unfortunately, the paper lacks examples showing that the stability definitions it presents are interesting ...

Nonstandard Analysis and Topology

1997
In what follows, I will use the phrase “In a nonstandard extension” to mean we employ a superstructure which is a nonstandard extension of the structure with which we are working. That structure will at least contain the real numbers. We will write *ℕ∞ for *ℕ\ℕ.

Robotic Extrusion of Architectural Structures with Nonstandard Topology

2018
This paper presents a fast and flexible method for robotic extrusion (or spatial 3D printing) of designs made of linear elements that are connected in nonstandard, irregular, and complex topologies. Nonstandard topology has considerable potential in design, both for visual effect and material efficiency, but usually presents serious challenges for ...
