A topological space $(X, T)$ with property $R$ is maximal $R$ (minimal $R$) if $T$ is a maximal (minimal) element in the set $R(X)$ of all topologies on the set $X ...

In mathematics and computer science, a directed acyclic graph, is a finite directed graph with no directed cycles. It consists of finitely many vertices and edges, with each edge directed from one ...

Topological order represents a fundamentally different paradigm of organising matter, one where long‐range entanglement and ground‐state degeneracy are determined by the global properties of the ...
