Global well posedness for the semilinear edge-degenerate parabolic equations on singular manifolds

open access: yesAdvances in Nonlinear Analysis, 2023
In this article, we study the long-time dynamical behavior of the solution for a class of semilinear edge-degenerate parabolic equations on manifolds with edge singularities. By introducing a family of potential well and compactness method, we reveal the

On Cauchy problem for fractional parabolic-elliptic Keller-Segel model

open access: yesAdvances in Nonlinear Analysis, 2022
In this paper, we concern about a modified version of the Keller-Segel model. The Keller-Segel is a system of partial differential equations used for modeling Chemotaxis in which chemical substances impact the movement of mobile species.

On the extinction problem for a p-Laplacian equation with a nonlinear gradient source

open access: yesOpen Mathematics, 2021
We deal with the extinction properties of the weak solutions for a p-Laplacian equation with a gradient nonlinearity. The critical extinction exponent is specified and the decay estimates of the extinction solutions are given.

Legendre-Chebyshev pseudo-spectral method for the diffusion equation with non-classical boundary conditions

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
The present paper is devoted to the numerical approximation for the diffusion equation subject to non-local boundary conditions. For the space discretization, we apply the Legendre-Chebyshev pseudospectral method, so that, the problem under consideration

A robust method of lines solution for singularly perturbed delay parabolic problem

open access: yesAlexandria Engineering Journal, 2020
A numerical method is proposed to solve a non-autonomous singularly perturbed parabolic differential equation with a time delay. The solution is obtained by a step by step discretisation process. First the spatial derivatives are discretised via a fitted

A second order finite difference scheme for singularly perturbed Volterra integro-differential equation

open access: yesAlexandria Engineering Journal, 2020
In this paper, a singularly perturbed Volterra integro-differential equation, characterised by a single layer, is investigated. A numerical technique which uses a non-standard finite difference scheme is implemented to solve the differential part ...
