The homology digraph of a preordered space [PDF]
, 2023 This paper studies a notion of directed homology for preordered spaces, called the homology digraph. We show that the homology digraph is a directed homotopy invariant and establish variants of the main results of ordinary singular homology theory for ...

On the use of partial orders in uniform spaces
Applied General Topology, 2003 We investigate the use of nets indexed by preorders in uniform spaces. Nine different Cauchy conditions and four different convergence conditions yield 36 completeness properties, each of which turns out to be equivalent to a known form of completeness ...

Profile Trees for Büchi Word Automata, with Application to Determinization [PDF]
Electronic Proceedings in Theoretical Computer Science, 2013 The determinization of Buchi automata is a celebrated problem, with applications in synthesis, probabilistic verification, and multi-agent systems. Since the 1960s, there has been a steady progress of constructions: by McNaughton, Safra, Piterman, Schewe,

Generalized Contractive Set-Valued Maps on Complete Preordered Quasi-Metric Spaces
Journal of Function Spaces and Applications, 2013 By using a suitable modification of the notion of a w-distance we obtain some fixed point results for generalized contractive set-valued maps on complete preordered quasi-metric spaces.

Key Practices of Knowledge Mobilization in Local Policy Settings
Public Administration Review, EarlyView.ABSTRACT The literature on knowledge mobilization (KM) acknowledges the complex processes involved in the application of evidence to policy. However, the everyday activities employed by knowledge mobilizers to facilitate these processes have proved difficult to capture and codify.

A class of semihypergroups connected to preordered weak Γ-semigroups [PDF]
, 2011 We introduce the concept of weak Γ-semigroups as a generalization of Γ-semigroups. Using preordered weak Γ-semigroups, we obtain a class of semihypergroups and we analyze them in this paper.

On the additive image of zeroth persistent homology
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

Machine learning modeling reveals unconventional nucleation mechanism in phase‐change material GeTe
InfoScience, Volume 3, Issue 3, September 2026.Machine‐learning molecular dynamics reveals that GeTe crystallization begins with Ge‐rich defective octahedral clusters, followed by Te‐mediated assembly into a rock‐salt network. This unconventional two‐stage nucleation pathway explains early Te sublattice ordering, Ge‐vacancy formation, and structural ordering kinetics in phase‐change materials ...
