Topological Space-Time Crystal [PDF]

Physical Review Letters, 2022
We introduce a new class of out-of-equilibrium noninteracting topological phases, the topological space-time crystals. These are time-dependent quantum systems which do not have discrete spatial translation symmetries, but instead are invariant under ...

Triangulating topological spaces

Proceedings of the tenth annual symposium on Computational geometry - SCG '94, 1994
Given a subspace [Formula: see text] and a finite set S⊆ℝd, we introduce the Delaunay complex, [Formula: see text], restricted by [Formula: see text]. Its simplices are spanned by subsets T⊆S for which the common intersection of Voronoi cells meets [Formula: see text] in a non-empty set. By the nerve theorem, [Formula: see text] and [Formula: see text]

L-topological spaces as spaces of points

Fuzzy Sets and Systems, 2011
In this paper, after defining the \(L\)-topological space \((X,\tau)\) in which \(L\) is a complete lattice the authors relate this concept to the corresponding classical notion of topological space by means of a fixed attachment in \(L\).

Topology and Topological Spaces

1997
We have now seen four different proofs of the Fundamental Theorem of Algebra. The first two were purely analysis, while the second pair involved a wide collection of algebraic ideas. However, we should realize that even in these algebraic proofs we did not totally leave analysis.

Ultracomplete Topological Spaces

Acta Mathematica Hungarica, 2001
If \(X\) is a set and \(\Sigma\) is a set of coverings of \(X\), then we can consider \((X,\Sigma)\) to be a generalized uniform space. This point of view originates from the work of \textit{J. W. Tukey} [Convergence and uniformity in topology, Princeton (1940)] who used \((X,\Sigma)\), where \(\Sigma\) fulfills some appropriate conditions, as another ...

Topological spaces of the web

Special interest tracks and posters of the 14th international conference on World Wide Web - WWW '05, 2005
We study the representation of space over the Web. Web’sspatiality is described by (hyper)links, and thus the webspace is given by a set of pages and links between them. Thecomplexity of this structure derives not only from the quan-tity, but also from the extreme dynamics that it presents.This structure is greatly influenced by its dynamics ...

On Chains of Topological Spaces

The Annals of Mathematics, 1938
complex. By a chain-complex L of T we shall mean a subcomplex of R. Meshes, chain-deformations, e or otherwise, said to be on 9?, are then defined in the natural way. The complex L is thus a chain-complex in the sense of No. 2, except that the (1)-chains and Kronecker-indices may now be elements of (M and not merely integers.

Metrization of Topological Spaces

Canadian Journal of Mathematics, 1951
A single valued function D(x, y) is a metric for a topological space provided that for points x, y, z of the space: 1. the equality holding if and only if x = y, 2. (symmetry), 3. (triangle inequality), 4.
