$C^{*}$ -correspondences for ordinal graphs

Benjamin Jones

We introduce a family of $C^{*}$ -correspondences $X_{α}$ naturally associated to every ordinal graph $Λ$ . When $Λ$ is a directed graph, $X_{0}$ is isomorphic to the usual $C^{*}$ -correspon…

Comparing Two Notions of Coaction Invariance of Ideals in $C^{*}$ -Algebras

Matthew Gillespie, Benjamin Jones, S. Kaliszewski +1

Given a coaction $δ$ of a locally compact group $G$ on a $C^{*}$ -algebra $A$ , we study the relationship between two different forms of coaction invariance of ideals of $A$ a…

Asymmetrically Weighted Dowker Persistence and Applications in Dynamical Systems

Tobias Timofeyev, Christopher Potvin, Benjamin Jones +3

By their nature it is difficult to differentiate chaotic dynamical systems through measurement. In recent years, work has begun on using methods of Topological Data Analysis (TDA)…
