On certain new exact solutions of a diffusive predator-prey system

open access: yes, 2012
We construct exact solutions for a system of two nonlinear partial differential equations describing the spatio-temporal dynamics of a predator-prey system where the prey per capita growth rate is subject to the Allee effect. Using the $\big(\frac{G'}{G}\

Auxiliary SDEs for homogenization of quasilinear PDEs with periodic coefficients

open access: yes, 2004
We study the homogenization property of systems of quasi-linear PDEs of parabolic type with periodic coefficients, highly oscillating drift and highly oscillating nonlinear term.

Exploration of nonlinear traveling wave phenomena in quintic conformable Benney-Lin equation within a liquid film

open access: yesAIMS Mathematics
In this article, we use the modified extended direct algebraic method (mEDAM) to explore and analyze the traveling wave phenomena embedded in the quintic conformable Benney-Lin equation (CBLE) that regulates liquid film dynamics.

Decay estimate of viscosity solutions of nonlinear parabolic PDEs and applications

open access: yesLe Matematiche, 2014
The aim of this paper is to establish a decay estimate for viscosity solutions of nonlinear PDEs. As an application we prove existence and uniqueness for time almost periodic viscosity solutions.

Solving parametric PDE problems with artificial neural networks

open access: yes, 2017
The curse of dimensionality is commonly encountered in numerical partial differential equations (PDE), especially when uncertainties have to be modeled into the equations as random coefficients.

Periodic solutions to a mean-field model for electrocortical activity

open access: yes, 2014
We consider a continuum model of electrical signals in the human cortex, which takes the form of a system of semilinear, hyperbolic partial differential equations for the inhibitory and excitatory membrane potentials and the synaptic inputs. The coupling

Asymptotic stability of breathers in some Hamiltonian networks of weakly coupled oscillators

open access: yes, 2012
We consider a Hamiltonian chain of weakly coupled anharmonic oscillators. It is well known that if the coupling is weak enough then the system admits families of periodic solutions exponentially localized in space (breathers).

Singularites in the Bousseneq equation and in the generalized KdV equation

open access: yes, 2001
In this paper, two kinds of the exact singular solutions are obtained by the improved homogeneous balance (HB) method and a nonlinear transformation. The two exact solutions show that special singular wave patterns exists in the classical model of some ...

The Perturbed Chen–Lee–Liu Equation: Diverse Optical Soliton Solutions and Other Wave Solutions

open access: yesAdvances in Mathematical Physics
The objective of the present study is to extract the optical soliton solutions (OSSs) of the perturbed Chen–Lee–Liu equation by exerting three techniques, which are the extended Wang’s direct mapping method, tanh/coth function method and the Subequation ...
