α-Integral Representation of The Solution for A Conformable Fractional Diffusion Operator and Basic Properties of The Operator

open access: yesCumhuriyet Science Journal, 2023
In this paper, we consider a diffusion operator which includes conformable fractional derivatives of order α (0<α≤1) instead of the ordinary derivatives in a traditional diffusion operator. We give an α-integral representation for the solution of this
