Fourier Spectral Methods for Some Linear Stochastic Space-Fractional Partial Differential Equations

open access: yesMathematics, 2016
Fourier spectral methods for solving some linear stochastic space-fractional partial differential equations perturbed by space-time white noises in the one-dimensional case are introduced and analysed.

Regularization and error estimates for nonhomogeneous backward heat problems

open access: yesElectronic Journal of Differential Equations, 2006
In this article, we study the inverse time problem for the non-homogeneous heat equation which is a severely ill-posed problem. We regularize this problem using the quasi-reversibility method and then obtain error estimates on the approximate ...

A nonhomogeneous backward heat problem: Regularization and error estimates

open access: yesElectronic Journal of Differential Equations, 2008
We consider the problem of finding the initial temperature, from the final temperature, in the nonhomogeneous heat equation $$displaylines{ u_t-u_{xx}= f(x,t),quad (x,t)in (0,pi)imes (0,T),\ u(0,t)= u(pi,t)= 0, quad (x,t) in (0,pi)imes(0,T ...

Novel Numerical Investigation of Reaction Diffusion Equation Arising in Oil Price Modeling

open access: yesMathematics
Consideration is given to a reaction–diffusion free boundary value problem with one or two turning points arising in oil price modeling. First, an exact (analytical) solution to the reduced problem (i.e., no diffusion term) was obtained for some given ...

Performance of a new stabilized structure-preserving finite element method for the Allen–Cahn equation

open access: yesMathematical and Computer Modelling of Dynamical Systems
This paper presents an energy stable scheme for the numerical solution of the Allen–Cahn equation. The scheme combines the Crank–Nicolson/Adams–Bashforth technique with the Galerkin method, complementing a thoughtfully designed stabilization term.
