Nonlinear deterministic equations in biological evolution [PDF]

Journal of Nonlinear Mathematical Physics, 2011
We review models of biological evolution in which the population frequency changes deterministically with time. If the population is self-replicating, although the equations for simple prototypes can be linearised, nonlinear equations arise in many ...

Soliton equations: admitted solutions and invariances via B\"acklund transformations [PDF]

Open Communications in Nonlinear Mathematical Physics
A couple of applications of B\"acklund transformations in the study of nonlinear evolution equations is here given. Specifically, we are concerned about third order nonlinear evolution equations.

Computation of traveling wave solution for nonlinear variable-order fractional model of modified equal width equation

AIMS Mathematics, 2021
The Variable-order fractional operators (VO-FO) have considered mathematically formalized recently. The opportunity of verbalizing evolutionary leading equations has led to the effective application to the modeling of composite physical problems ranging ...

Reductions and Conservation Laws of a Generalized Third-Order PDE via Multi-Reduction Method

Mathematics, 2022
In this work, we consider a family of nonlinear third-order evolution equations, where two arbitrary functions depending on the dependent variable appear. Evolution equations of this type model several real-world phenomena, such as diffusion, convection,

Abelian versus non-Abelian Baecklund Charts: some remarks [PDF]

, 2018
Connections via Baecklund transformations among different non-linear evolution equations are investigated aiming to compare corresponding Abelian and non Abelian results. Specifically, links, via Baecklund transformations, connecting Burgers and KdV-type

Blowup and MLUH stability of time-space fractional reaction-diffusion equations

Electronic Research Archive, 2022
In this paper, we consider a class of nonlinear time-space fractional reaction-diffusion equations by transforming the time-space fractional reaction-diffusion equations into an abstract evolution equations in a fractional Sobolev space.
