Exp-function Method and Reduction Transformations for Rogue ‎Wave Solutions of the Davey-Stewartson Equations‎ [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
A pair of rogue wave solutions of the Davey-Stewartson (DS) equations are obtained by using the exp-function method and reduction transformations. Firstly, the Davey-Stewartson equations are transformed into two easy-to-solve equations, one of which is ...

Non-Autonomous Evolutionary Equations [PDF]

open access: yes, 2021
AbstractPreviously, we focussed on evolutionary equations of the form $$\displaystyle \left (\overline {\partial _{t,\nu }M(\partial _{t,\nu })+A}\right )U=F. $$ ∂

A Schrödinger Equation for Evolutionary Dynamics

open access: yesQuantum Reports, 2023
We establish an analogy between the Fokker–Planck equation describing evolutionary landscape dynamics and the Schrödinger equation which characterizes quantum mechanical particles, showing that a population with multiple genetic traits evolves analogously to a wavefunction under a multi-dimensional energy potential in imaginary time.

5D Nonlinear Dynamic Evolutionary System in Real Estate Market

open access: yesComplexity, 2021
In this paper, we propose a new predator-prey nonlinear dynamic evolutionary model of real estate enterprises considering the large, medium, and small real estate enterprises for three different prey teams.

The Price equation and evolutionary epidemiology

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2020
The Price equation has found widespread application in many areas of evolutionary biology, including the evolutionary epidemiology of infectious diseases. In this paper, we illustrate the utility of this approach to modelling disease evolution by first deriving a version of Price’s equation that can be applied in continuous time and to populations with

Replicator Dynamics and Evolutionary Stable Strategies in Heterogeneous Games [PDF]

open access: yes
We generalise and extend the work of Iñarra and Laruelle (2011) by studying two person symmetric evolutionary games with two strategies, a heterogenous population with two possible types of individuals and incomplete information.

Dynamics of Evolutionary Differential Equations with Several Spatial Variables

open access: yesMathematics, 2023
The article is devoted to a method for constructing exact and approximate solutions of evolutionary partial differential equations with several spatial variables. The method is based on the theory of completely integrable distributions.

Matrix Equation Techniques for Certain Evolutionary Partial Differential Equations [PDF]

open access: yesJournal of Scientific Computing, 2021
AbstractWe show that the discrete operator stemming from time-space discretization of evolutionary partial differential equations can be represented in terms of a single Sylvester matrix equation. A novel solution strategy that combines projection techniques with the full exploitation of the entry-wise structure of the involved coefficient matrices is ...

Notes on spectrum and exponential decay in nonautonomous evolutionary equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We first determine the dichotomy (Sacker-Sell) spectrum for certain nonautonomous linear evolutionary equations induced by a class of parabolic PDE systems.
