Topology of matching complexes of complete graphs via discrete Morse theory [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
Bouc (1992) first studied the topological properties of $M_n$, the matching complex of the complete graph of order $n$, in connection with Brown complexes and Quillen complexes. Bj\"{o}rner et al. (1994) showed that $M_n$ is homotopically $(\nu_n-1)$

Existence and Multiplicity of Solutions for Discrete Nonlinear Two-Point Boundary Value Problems

open access: yesDiscrete Dynamics in Nature and Society, 2011
By using Morse theory, the critical point theory, and the character of 𝐾1/2, we consider the existence and multiplicity results of solutions to the following discrete nonlinear two-point boundary value problem βˆ’Ξ”2π‘₯(π‘˜βˆ’1)=𝑓(π‘˜,π‘₯(π‘˜)),π‘˜βˆˆβ„€(1,𝑇) subject to π‘₯(0)=

Adaptive Discrete Vector Field in Sensor Networks

open access: yesSensors, 2018
Homology groups are a prime tool for measuring the connectivity of a network, and their computation in a distributed and adaptive way is mandatory for their use in sensor networks.

The minimal cellular resolutions of the edge ideals of forests [PDF]

open access: yes, 2019
We present an explicit construction of a minimal cellular resolution for the edge ideals of forests, based on discrete Morse theory. In particular, the generators of the free modules are subsets of the generators of the modules in the Lyubeznik ...

Automatic Detection of Cross-Shaped Targets for Laser Scan Registration

open access: yesIEEE Access, 2018
Laser scan registration estimates a relative transformation to match one scan with another, based on the shape of the overlapping portions of the scans. The core and challenging problem of scan registration in a large-scale scene is, how to detect public

Membrane parallelism for discrete Morse theory applied to digital images [PDF]

open access: yes, 2015
In this paper, we propose a bio-inspired membrane computational framework for constructing discrete Morse complexes for binary digital images. Our approach is based on the discrete Morse theory and we work with cubical complexes.

Estimate of Number of Periodic Solutions of Second-Order Asymptotically Linear Difference System

open access: yesAbstract and Applied Analysis, 2013
We investigate the number of periodic solutions of second-order asymptotically linear difference system. The main tools are Morse theory and twist number, and the discussion in this paper is divided into three cases. As the system is resonant at infinity,
