We introduce the shift-dimension of multipersistence modules and investigate its algebraic properties. This gives rise to a new invariant of multigraded modules over the multivariate polynomial ring arising from the hierarchical stabilization of the zeroth total multigraded Betti number. We present a fast algorithm for the computation of the shift-dimension of interval modules in the bivariate case. We construct multipersistence contours that are parameterized by multivariate functions and…

The theory of multidimensional persistence
TLDR
This paper proposes the rank invariant, a discrete invariant for the robust estimation of Betti numbers in a multifiltration, and proves its completeness in one dimension.
The representation theorem of persistence revisited and generalized
TLDR
This work gives a more accurate statement of the original Representation Theorem and provides a complete and self-contained proof and generalizes the statement from the case of linear sequences of R- modules to R-modules indexed over more general monoids.
Multidimensional Persistence and Noise
TLDR
The feature counting invariant is introduced and it is proved that assigning this invariant to compact tame functors is a 1-Lipschitz operation.
Metrics for Generalized Persistence Modules
TLDR
This work considers the question of defining interleaving metrics on generalized persistence modules over arbitrary preordered sets, and introduces a distinction between ‘soft’ and ‘hard’ stability theorems.
Stratifying Multiparameter Persistent Homology
TLDR
This work proposes multigrade Hilbert series, multigraded associated primes and local cohomology as invariants for studying multiparameter persistent homology, which generalize in a suitable sense the invariant for the one-parameter case.
Decomposition of persistence modules
We show that a pointwise finite-dimensional persistence module indexed over a small category decomposes into a direct sum of indecomposables with local endomorphism rings. As an application of this…

Persistence Modules on Commutative Ladders of Finite Type
TLDR
It is proved that the commutative ladders of length less than 5 are representation-finite and explicitly show their Auslander–Reiten quivers.
Fast Minimal Presentations of Bi-graded Persistence Modules
TLDR
This work proposes the use of priority queues to avoid extensive scanning of the matrix columns, which constitutes the computational bottleneck in the LW-algorithm, and combines their algorithm with ideas from the multi-parameter chunk algorithm by Fugacci and Kerber.
