DETERMINATION OF A NONLINEAR SOURCE TERM IN A REACTION-DIFFUSION EQUATION BY USING FINITE ELEMENT METHOD AND RADIAL BASIS FUNCTIONS METHOD

In this paper, two numerical methods are presented to solve a nonlinear inverse parabolic problem of determining the unknown reaction term in the scalar reaction-diffusion equation. In the first method, the finite element method will be used to discretize the variational form of the problem and in t...
