Discretized fractional substantial calculus∗
Received: 5 January 2014
Revised: 15 August 2014
This paper discusses the properties and the numerical discretizations of the fractional substantial integral and the fractional substantial derivative where , σ can be a constant or a function not related to x, say σ(y); and m is the smallest integer that exceeds μ. The Fourier transform method and fractional linear multistep method are used to analyze the properties or derive the discretized schemes. And the convergences of the presented discretized schemes with the global truncation error (p = 1,2,3,4,5) are theoretically proved and numerically verified.
