Asymptotic stability of solutions for a diffusive epidemic model
Demonstratio Mathematica, 2022 The aim of this paper is to study the existence and the asymptotic stability of solutions for an epidemiologically emerging reaction-diffusion model. We show that the model has two types of equilibrium points to resolve the proposed system for a fairly ...

Equilibrium Point Control Cannot be Refuted by Experimental Reconstruction of Equilibrium Point Trajectories [PDF]
Journal of Neurophysiology, 2007 In the literature, it has been hotly debated whether the brain uses internal models or equilibrium point (EP) control to generate arm movements. EP control involves specification of EP trajectories, time series of arm configurations in which internal forces and external forces are in equilibrium; if the arm is not in a specified EP, it is driven ...

Mathematics, 2022 A non-linear fractional Selkov dynamic system for mathematical modeling of microseismic phenomena is proposed. This system is a generalization of the previously known Selkov system, which has self-oscillatory modes and is used in biology to describe ...

Dynamics of General Class of Difference Equations and Population Model with Two Age Classes
Mathematics, 2020 In this paper, we study the qualitative behavior of solutions for a general class of difference equations. The criteria of local and global stability, boundedness and periodicity character (with period 2 k ) of the solution are established ...

Axioms, 2021 We have obtained a new class of ordered pairs of multivalued maps that have pairs of coupled fixed points. We illustrate the main result with two examples that cover a wide range of models.

A variational principle, coupled fixed points and market equilibrium
Nonlinear Analysis, 2021 We present a possible kind of generalization of the notion of ordered pairs of cyclic maps and coupled fixed points and its application in modelling of equilibrium in oligopoly markets.

Equilibrium points of random generalized games
International Journal of Mathematics and Mathematical Sciences, 1998 In this paper, the concepts of random maximal elements, random equilibria and random generalized games are described. Secondly by measurable selection theorem, some existence theorems of random maximal elements for Lc-majorized correspondences are ...

Is the forest biomass a key regulator of global warming?: A mathematical modelling study
Geology, Ecology, and Landscapes, 2022 In this article, a mathematical model has been formulated by considering forest biomass and global warming as a separate compartment. It is assumed that the forest biomass follow logistic growth in the absence of global warming.

Noncompact Equilibrium Points for Set-Valued Maps
Abstract and Applied Analysis, 2014 We prove a generalized result on the existence of equilibria for a monotone set-valued map defined on noncompact domain and take its values in an order of topological vector space. As consequence, we give a new variational inequality.
