Homological algebra of modules over posets

E Miller - arXiv preprint arXiv:2008.00063, 2020 - arxiv.org
Homological algebra of modules over posets is developed, as closely parallel as possible to
that of finitely generated modules over noetherian commutative rings, in the direction of finite …

Approximation by interval-decomposables and interval resolutions of persistence modules

H Asashiba, EG Escolar, K Nakashima… - Journal of Pure and …, 2023 - Elsevier
In topological data analysis, two-parameter persistence can be studied using the
representation theory of the 2d commutative grid, the tensor product of two Dynkin quivers of …

Decomposition of zero-dimensional persistence modules via rooted subsets

ÁJ Alonso, M Kerber - arXiv preprint arXiv:2303.06118, 2023 - arxiv.org
We study the decomposition of zero-dimensional persistence modules, viewed as functors
valued in the category of vector spaces factorizing through sets. Instead of working directly at …

Generic multi-parameter persistence modules are nearly indecomposable

U Bauer, L Scoccola - arXiv preprint arXiv:2211.15306, 2022 - arxiv.org
We study the interplay between algebraic and metric properties of multi-parameter
persistence modules (linear representations of the poset $\mathbf {R}^ n $ with $ n\geq 2$) …

Meta-diagrams for 2-parameter persistence

N Clause, TK Dey, F Mémoli, B Wang - arXiv preprint arXiv:2303.08270, 2023 - arxiv.org
We first introduce the notion of meta-rank for a 2-parameter persistence module, an invariant
that captures the information behind images of morphisms between 1D slices of the module …

The shift-dimension of multipersistence modules

W Chachólski, R Corbet, AL Sattelberger - Journal of Applied and …, 2024 - Springer
We present the shift-dimension of multipersistence modules and investigate its algebraic
properties. This gives rise to a new invariant of multigraded modules over the multivariate …

Hyperplane Restrictions of Indecomposable -Dimensional Persistence Modules

S Moore - arXiv preprint arXiv:2011.00339, 2020 - arxiv.org
Understanding the structure of indecomposable $ n $-dimensional persistence modules is a
difficult problem, yet is foundational for studying multipersistence. To this end, Buchet and …

The combinatorics of tensor products of higher Auslander algebras of type A

J McMahon, NJ Williams - Glasgow Mathematical Journal, 2021 - cambridge.org
We consider maximal non-l-intertwining collections, which are a higher-dimensional version
of the maximal non-crossing collections which give clusters of Plücker coordinates in the …

Notes on Pointwise Finite-Dimensional -Parameter Persistence Modules

W Li, M Ozaydin - arXiv preprint arXiv:2404.13877, 2024 - arxiv.org
In this paper, we study pointwise finite-dimensional (pfd) $2 $-parameter persistence
modules where each module admits a finite convex isotopy subdivision. We show that a pfd …

Decomposition and Stability of Multiparameter Persistence Modules

C Xin - 2023 - search.proquest.com
In the contemporary computing landscape, the effective utilization of data has emerged as a
primary driving force. Nonetheless, handling data with intricate structures, non-Euclidean …
