Higher order linear parabolic equations [PDF]

open access: yes, 2012
We first highlight the main differences between second order and higher order linear parabolic equations. Then we survey existing results for the latter, in particular by analyzing the behavior of the convolution kernels.

Initial-boundary value problem for higher-orders nonlinear elliptic-parabolic equations with variable exponents of the nonlinearity in unbounded domains without conditions at infinity

open access: yesМатематичні Студії, 2023
Initial-boundary value problems for parabolic and elliptic-parabolic (that is degenerated parabolic) equations in unbounded domains with respect to the spatial variables were studied by many authors.

Closed-form solutions of higher order parabolic equations in multiple dimensions: A reliable computational algorithm

open access: yesAlexandria Engineering Journal, 2023
Parabolic equations play an important role in chemical engineering, vibration theory, particle diffusion and heat conduction. Solutions of such equations are required to analyze and predict changes in physical systems. Solutions of such equations require

Galerkin-Petrov method for one-dimensional parabolic equations of higher order in domain with a moving boundary [PDF]

open access: yesКомпьютерные исследования и моделирование, 2013
In the current paper, we study a Galerkin-Petrov method for a parabolic equations of higher order in domain with a moving boundary. Asymptotic estimates for the convergence rate of approximate solutions are obtained.

Numerical solutions to low and high-dimensional Allen–Cahn equations using stochastic differential equations and neural networks

open access: yesPartial Differential Equations in Applied Mathematics, 2023
In this paper, we focus on solving semilinear parabolic differential equations in low and high-dimensional spaces by using backward stochastic differential equations and deep neural networks (the BSDE solver introduced by Han et al. in 2017).

Initial boundary value problem for a class of higher-order n-dimensional nonlinear pseudo-parabolic equations

open access: yesBoundary Value Problems, 2021
In this paper, we study the initial boundary value problem for a class of higher-order n-dimensional nonlinear pseudo-parabolic equations which do not have positive energy and come from the soil mechanics, the heat conduction, and the nonlinear optics ...

On Oscillations in a Gene Network with Diffusion

open access: yesMathematics, 2023
We consider one system of partial derivative equations of the parabolic type as a model of a simple 3D gene network in the presence of diffusion of its three components.
