Discrete Morse Functions and Watersheds

open access: yesJournal of Mathematical Imaging and Vision, 2023
Abstract Any watershed, when defined on a stack on a normal pseudomanifold of dimension d, is a pure (d-1)-subcomplex that satisfies a drop-of-water principle. In this paper, we introduce Morse stacks, a class of functions that are equivalent to discrete Morse functions.

Umbilical Submanifolds and Morse Functions [PDF]

open access: yesNagoya Mathematical Journal, 1972
Let Mn be a differentiable manifold (of class C∞). By a Morse function on Mn we mean a differentiable function whose critical points are all non-degenerate. If f is an immersion of Mn into a Euclidean space Rm, we may obtain Morse functions on Mn in the following way.

Approximation of electronic term of diatomic molecule by the Morse function. The role of anharmonicity [PDF]

open access: yes, 2023
This article presents an extension of the report made at the 2nd International Symposium "Non-Covalent Interactions" 10/14/22 in Moscow. That report outlined the basic principles of modeling the potential function of diatomic molecules using the Morse ...

The computation of the index of a Morse function at a critical point

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
A theoretical approach in computing the index of a Morse function at a critical point on a real non-singular hypersurface V is given. As a consequence the Euler characteristic of V is computed. In the case where the hypersurface is polynomial and compact,

Computing Persistent Homology by Spanning Trees and Critical Simplices

open access: yesResearch, 2023
Topological data analysis can extract effective information from higher-dimensional data. Its mathematical basis is persistent homology. The persistent homology can calculate topological features at different spatiotemporal scales of the dataset, that is,

Witten-Morse functions and Morse inequalities on digraphs

open access: yes, 2021
In this paper, we prove that discrete Morse functions on digraphs are flat Witten-Morse functions and Witten complexes of transitive digraphs approach to Morse complexes. We construct a chain complex consisting of the formal linear combinations of paths which are not only critical paths of the transitive closure but also allowed elementary paths of the

Topology of optimal flows with collective dynamics on closed orientable surfaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2020
We consider flows on a closed surface with one or more heteroclinic cycles that divide the surface into two regions. One of the region has gradient dynamics, like Morse fields.
