Nontrivial periodic solutions to delay difference equations via Morse theory
Open Mathematics, 2018 In this paper some sufficient conditions are obtained to guarantee the existence of nontrivial 4T + 2 periodic solutions of asymptotically linear delay difference equations. The approach used is based on Morse theory.

Discrete microlocal Morse theory
Journal of Pure and Applied AlgebraWe establish several results combining discrete Morse theory and microlocal sheaf theory in the setting of finite posets and simplicial complexes. Our primary tool is a computationally tractable description of the bounded derived category of sheaves on a poset with the Alexandrov topology. We prove that each bounded complex of sheaves on a finite poset

Arthritis &Rheumatology, Accepted Article.Objectives Sjögren's disease (SjD) is a heterogeneous autoimmune disorder characterized by substantial clinical and molecular diversity. This heterogeneity raises key questions regarding the existence of distinct pathogenic mechanisms underlying disease subtypes.

Existence of acyclic matching and Morse complex on transitive digraphs
AKCE International Journal of Graphs and CombinatoricsFor any digraph, there exists a transitive closure. The transitive digraph is a discrete geometric object which has a close relationship with simplicial complex.

Complete solution of the Marchenko equation for a simple model system; pp. 267–283 [PDF]
Proceedings of the Estonian Academy of Sciences, 2016 An example of full solution of the inverse scattering problem on the half line (from 0 to â) is presented. For this purpose, a simple analytically solvable model system (Morse potential) is used, which is expected to be a reasonable approximation to a ...

Multiparameter discrete Morse theory
Journal of Applied and Computational TopologyThe main objective of this paper is to extend Morse-Forman theory to vector-valued functions. This is mostly motivated by the need to develop new tools and methods to compute multiparameter persistence. To generalize the theory, in addition to adapting the main definitions and results of Forman to this vectorial setting, we use concepts of ...

Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

مجلة التربية والعلم, 2019 In this research, Morse code was introduced in a new type, which we called the hybrid to be appropriate between the code itself and the theory of fragmentation, which could later be used as a type of encryption in messages between two or more parties.
