The AdS/CFT Correspondence Conjecture and Topological Censorship [PDF]

open access: yes, 1999
In gr-qc/9902061 it was shown that (n+1)-dimensional asymptotically anti-de-Sitter spacetimes obeying natural causality conditions exhibit topological censorship.

Some Problems of Topology Change Description in the Theory of Space-Time [PDF]

open access: yes, 1995
The problem of topology change description in gravitation theory is analized in detailes. It is pointed out that in standard four-dimensional theories the topology of space may be considered as a particular case of boundary conditions (or constraints ...

Du trimorphe aux frontières quasi topologiques

open access: yesAteliers d'Anthropologie, 2012
Topology is used in linguistics for semantic, lexical and grammatical descriptions. However, classical topology, with its notion of the limit, is insufficient. Therefore, to describe numerous semantic oppositions (such as “again” / “not again”, “already”

Generic Stationary Measures and Actions [PDF]

open access: yes, 2015
Let $G$ be a countably infinite group, and let $\mu$ be a generating probability measure on $G$. We study the space of $\mu$-stationary Borel probability measures on a topological $G$ space, and in particular on $Z^G$, where $Z$ is any perfect Polish ...

An Algorithm to Translate Building Topology in Building Information Modeling into Object-Oriented Physical Modeling-Based Building Energy Modeling

open access: yesEnergies, 2016
This paper presents an algorithm to translate building topology in an object-oriented architectural building model (Building Information Modeling, BIM) into an object-oriented physical-based energy performance simulation by using an object-oriented ...

Towards Bulk Metric Reconstruction from Extremal Area Variations [PDF]

open access: yes, 2019
The Ryu-Takayanagi and Hubeny-Rangamani-Takayanagi formulae suggest that bulk geometry emerges from the entanglement structure of the boundary theory. Using these formulae, we build on a result of Alexakis, Balehowsky, and Nachman to show that in four ...

Equivalent topologies on the contracting boundary

open access: yesGlasnik Matematicki, 2023
The contracting boundary of a proper geodesic metric space generalizes the Gromov boundary of a hyperbolic space. It consists of contracting geodesics up to bounded Hausdorff distances. Another generalization of the Gromov boundary is the \(\kappa\)–Morse boundary with a sublinear function \(\kappa\).

A metrizable topology on the contracting boundary of a group [PDF]

open access: yesTransactions of the American Mathematical Society, 2019
The ‘contracting boundary’ of a proper geodesic metric space consists of equivalence classes of geodesic rays that behave like rays in a hyperbolic space. We introduce a geometrically relevant, quasi-isometry invariant topology on the contracting boundary. When the space is the Cayley graph of a finitely generated group we show that our new topology is

A Theoretical Investigation of Flow Topologies in Bubble- and Droplet-Affected Flows

open access: yesFluids, 2019
A local flow topology analysis was conducted for laminar particle-affected flows. Based on the invariants of the velocity gradient tensor, all possible flow structures can be categorized into two focal and two nodal topologies for incompressible flows ...
