Özet

The study in this paper mainly concerns the inverse problem of determining an unknown source function in the linear fractional differential equation with variable coefficient using Adomian decomposition method (ADM). We apply ADM to determine the continuous right hand side functions.. f(x) and f(t) in the heat-like diffusion equations D(t)(alpha)u(x, t) = h (x)u(xx)(x, t) +f(x) and f(x) (..,..) = h (x)u(xx)(x, t) + f(t), respectively. The results reveal that ADM is very effective and simple for the inverse problem of determining the source function.
