Abstract
The current study is conducted to evaluate the numerical solution of the space-time fractional Klein-Gordon equation. This equation is obtained by adopting the generalized Caputo fractional derivative instead of the classical integer order derivative. The significant benefit of fractional derivatives is their nonlocal property and the capability to provide detailed and precise analysis of the model. The novel collocation technique, which is capable of dealing with space-time fractional derivatives simultaneously, has been implemented to evaluate the numerical solution for the fractional Klein Gordon equation. In this technique, the discretizations for time and space do not depend on each other, which is its most significant advantage. Hence, we have the liberty to employ two different basis functions, namely radial basis functions and the Chebyshev polynomials in space and time, respectively. The convergence, stability, and consistency of the method are also discussed. The results acquired by the implemented technique have been compared with other approaches to prove the efficiency and applicability of the proposed method.
