Analysis of the Convergence and Periodicity of a Rational Difference Equation
Journal of Mathematical Sciences and Modelling, 2019 The exact solutions of most difference equations cannot be obtained sometimes. This can be attributed to the fact that there is no a specific approach from which one can find the exact solution.

Many-body localization: stability and instability [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2017 Rare regions with weak disorder (Griffiths regions) have the potential to spoil localization. We describe a non-perturbative construction of local integrals of motion (LIOMs) for a weakly interacting spin chain in one dimension, under a physically reasonable assumption on the statistics of eigenvalues.

The effects of evolution on the stability of competing species
Journal of Biological Dynamics, 2022 Based on evolutionary game theory and Darwinian evolution, we propose and study discrete-time competition models of two species where at least one species has an evolving trait that affects their intra-specific, but not their inter-specific competition ...

Local stability implies global stability for the 2-dimensional Ricker map [PDF]
, 2012 Consider the difference equation $x_{k+1}=x_k e^{\alpha-x_{n-d}}$ where $\alpha$ is a positive parameter and d is a non-negative integer. The case d = 0 was introduced by W.E. Ricker in 1954. For the delayed version d >= 1 of the equation S. Levin and R.

A Dynamic SIqIRV Mathematical model with Non-linear Force of Isolation, Infection and Cure
Nonautonomous Dynamical Systems, 2022 The Susceptible-Isolated-Infected-Recovered-Vaccinated (SIqIRV) deterministic model is examined in this paper. This model considers a nonlinear force of quarantine, infection and care, where vaccinated individuals lose their immunity after a period of ...
