PERSISTENT MAYER HOMOLOGY AND PERSISTENT MAYER LAPLACIAN.

Abstract

In algebraic topology, the differential (i.e., boundary operator) typically satisfies $d^2=0$ . However, the generalized differential $d^N=0$ for an integer $N\ge 2$ has been studied in terms of Mayer homology on $N$ -chain complexes for more than eighty years. We introduce Mayer Laplacians on $N$ -chain complexes. We show that both Mayer homology and Mayer Laplacians offer considerable application potential, providing topological and geometric insights to spaces. We also introduce persistent Mayer homology and persistent Mayer Laplacians at various $N$ . The bottleneck distance and stability of persistence diagrams associated with Mayer homology are investigated. Our computational experiments indicate that the topological features offered by persistent Mayer homology and spectrum given by persistent Mayer Laplacians hold substantial promise for large, complex, and diverse data. We envision that the present work serves as an inaugural step towards integrating Mayer homology and Mayer Laplacians into the realm of topological data analysis.
