One-dimensional reduction of multidimensional persistent homology

  title={One-dimensional reduction of multidimensional persistent homology},
  author={Francesca Cagliari and Barbara Di Fabio and Massimo Ferri},
A recent result on size functions is extended to higher homology modules: the persistent homology based on a multidimensional measuring function is reduced to a 1-dimensional one. This leads to a stable distance for multidimensional persistent homology. Some reflections on i-essentiality of homological critical values conclude the paper.

Multidimensional persistent homology is stable
Multidimensional persistence studies topological features of shapes by analyzing the lower level sets of vector-valued functions. The rank invariant completely determines the multidimensional
Persistent homology and applied homotopy theory
This paper is a survey of persistent homology, primarily as it is used in topological data analysis. It includes the theory of persistence modules, as well as stability theorems for persistence
The Persistence Space in Multidimensional Persistent Homology
The persistence space of a vector-valued continuous function is introduced to generalize the concept of persistence diagram in this sense and a method to visualize topological features of a shape via persistence spaces is presented.
Stable Comparison of Multidimensional Persistent Homology Groups with Torsion
A pseudo-distance dT is introduced that represents a possible solution to the present lack of a stable method to compare persistent homology groups with torsion, and the main theorem proves the stability of the new pseudo- distance with respect to the change of the filtering function.

Invariance properties of the multidimensional matching distance in Persistent Topology and Homology
This paper shows that the multidimensional matching distance is actually invariant with respect to such a choice, and formally depends on a subset of $\R^n\times-valued filtering functions inducing a parameterization of these half-planes.
A Global Method for Reducing Multidimensional Size Graphs
A global method for reducing size graphs is presented, together with a theorem stating that size graphs reduced in such a way preserve all the information in terms of multidimensional size functions.
Relative Embedded Homology of Hypergraphs
In this paper, we generalize the embedded homology in [1] for hypergraphs and study the relative embedded homology for hypergraph pairs. We study the topology for sub-hypergraphs. Using the relative


A refinement of multi-dimensional persistence
We study the multi-dimensional persistence of Carlsson and Zomorodian and obtain a finer classification based upon the higher tor-modules of a persistence module. We propose a variety structure on
Persistent Homology — a Survey
Persistent homology is an algebraic tool for measuring topological features of shapes and functions. It casts the multi-scale organization we frequently observe in nature into a mathematical
The theory of multidimensional persistence
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.
Stability of persistence diagrams
The persistence diagram of a real-valued function on a topological space is a multiset of points in the extended plane. We prove that under mild assumptions on the function, the persistence diagram
Size Functions from a Categorical Viewpoint
A new categorical approach to size functions is given. Using this point of view, it is shown that size functions of a Morse map, f: M→ℜ can be computed through the 0-dimensional homology. This result
Stability in multidimensional Size Theory
This paper proves that in Size Theory the comparison of multidimensional size functions can be reduced to the 1-dimensional case by a suitable change of variables. Indeed, we show that a foliation in
Necessary Conditions for Discontinuities of Multidimensional Size Functions
Some new results about multidimensional Topological Persistence are presented, proving that the discontinuity points of a $k$-dimensional size function are necessarily related to the pseudocritical
Topological Persistence and Simplification
Fast algorithms for computing persistence and experimental evidence for their speed and utility are given for topological simplification within the framework of a filtration, which is the history of a growing complex.
Size homotopy groups for computation of natural size distances
For every manifold M endowed with a structure described by a function from M to the vector space R k , a parametric family of groups, called size homotopy groups, is introduced and studied. Some

A distance is defined on the quotient of the set of submanifolds of a Euclidean space, with respect to similarity. It is then related to a previously defined function which captures the metric
