Nonexpansive Bijections in $T_{0}$ -Quasi-Metric Spaces and Their $q$ -Hyperconvex Hulls

Collins Amburo Agyingi

We study bijective nonexpansive maps in $T_{0}$ -quasi-metric spaces, distinguishing preservation of directed distances from pointwise rigidity. Our focus is their behaviour under pas…

A Persistent Homology Signature of Knotting

Aurelie Jodelle Kemme, Collins A. Agyingi, Colleen Farrelly +1

We ask whether knotting can be recognised using persistent homology. Starting from a point-cloud representation of a curve, we compute one-dimensional persistent homology, extract…
