Invariants of persistence modules defined by order-embeddings
Claire Amiot, Thomas Brüstle, Eric J. Hanson
One of the main objectives of topological data analysis is the study of discrete invariants for persistence modules, in particular when dealing with multiparameter persistence modu…

Generalized Rank via Minimal Subposet
Thomas Brüstle, Thomas Brüstle, Justin Desrochers +1
Let be a small, connected category with finite hom-sets. We show that if the embedding of a connected subcategory is both initial and final, then the re…

An exact structure approach to almost rigid modules over quivers of type
Thomas Brüstle, Eric J. Hanson, Sunny Roy +1
Let be the path algebra of a quiver of Dynkin type . The module category has a combinatorial model as the category of diagonals in a polygon w…
