abstract
The goal of this work is to extend the standard persistent homology pipeline for exploratory data analysis to the 2-D persistence setting, in a practical, computationally efficient way. To this end, we introduce RIVET, a software tool for the visualization of 2-D persistence modules, and present mathematical foundations for this tool. RIVET provides an interactive visualization of the barcodes of 1-D affine slices of a 2-D persistence module $M$. It also computes and visualizes the dimension of each vector space in $M$ and the bigraded Betti numbers of $M$. At the heart of our computational approach is a novel data structure based on planar line arrangements, on which we can perform fast queries to find the barcode of any slice of $M$. We present an efficient algorithm for constructing this data structure and establish bounds on its complexity.

For any fixed c ≥ 1, there exist finite metric spaces whose Vietoris-Rips filtration cannot be c-approximated by any finitely presented construction of linear size; for c < √2, exponential size is required.
Constructs a computable 3-parameter Delaunay trifiltration for bifunction point clouds with O(|X|^⌈(d+1)/2⌉+1) size, an O(|X|^⌈d/2⌉+2) algorithm, and experiments on thousands of R³ points.
Interleaving distance on single- and multi-parameter persistence modules equals a Galois-edit distance, yielding a new proof of bottleneck stability.
Galois connections provide a new language that unifies interleavings and matchings in persistent homology and yields a simpler proof of bottleneck stability.
New algorithms compute Hom spaces for poset representations in O(n^4 (thick(Y) + thick(Omega^1 Y))^2) time using a uniqueness result for lifts, plus a classical O(n^3 thick(Y)^3) method, both improving on O(n^6) and strengthening AIDA for multiparameter persistence.
A new functor calculus for posets yields necessary and sufficient conditions for n-parameter multipersistence modules to have projective dimension at most n-1 or n-2.

Introduces a multi-parameter persistence extension of partial functions on dynamical systems to construct three-parameter filtrations identifying optimal ε-perturbation paths minimizing h.
Introduces a gauge-geometry framework that computes curvature and holonomy of Hodge zero-mode transport to detect structural changes in parameter-dependent topological data.
Develops invariants for persistence modules over posets P by restricting to order-embedded finite-representation-type subposets X, decomposing into indecomposables, and generalizing signed barcodes via homological methods.
Persistent homology on the ORBIS Roman trade network with a differential friction model detects three phases of network cycle redundancy in the Eastern Mediterranean, showing recoverable stress in the third century but monotonic decline after 290 CE.
