New Exact Solutions of Time Conformable Fractional Klein Kramer Equation

The Klein Krames equation (KKE) stands for the probability distribution function (PDF) that describes the diffusion of particles subjected an external force. It is shown that 2 A. A. Alderremy, H. I. Abdel-Gawad, Khaled M. Saad, Shaban Aly the conformable fractional derivative (CFD) KKE can be reduced to the classical one's by using similarity transformations. Here, the objective of this work is to find the exact solutions of CFD-KKE.. To this issue, an approach is presented. It is based on transforming the KKE to a system of first order PDEs. The solutions are found by implementing extended unified method. It is found that, the integrability condition is that the external force is constant. The numerical results of the solutions are calculated and the are shown graphically. 2020 Mathematics Subject Classification: 34A08; 35A22; 41A30; 65N22.
