In such cases α should be taken between 0 and 1, and Riemann-Liouvelli fractional derivatives should be properly combined (composed) with integer order derivatives with considered definition (of composition). 2 gives fractional RL derivatives with lower terminal at − ∞ . In the list H (t) is unit step Heaviside function. E is Mittag-Leffler function, ψ -is ‘psi’ function. These tables’ gives a feel of how fractional differintegration will look like in analytical expressions. We demonstrate the derivative calculation of Dirac’s delta function δ ( x − c) with b ≤ c ≤ d , defined by d ∫ δ ( x − c) f ( x)dx = f (c) b Using { } Dxq+ x u = Γ(u + 1) u − q x .

A very recent approach to solve General Dynamic Systems with action reaction process is described in the Chapter-11, which gives approximate analytic solution close to physics; the mathematics of Adomian Decomposition Method is applied to describe the physical reaction chain. A simple examples in this section elaborates the concept of Fractional Differential equation. 1 Abel’s Fractional Integral Equation of Tautochrone The Abel’s problem is to find a curve where the time of decent is same irrespective of the position of release of ball in frictionless system.

S. Miller and B. Dα n f (t ) α = α1 + α 2 + ... + α n αi < 1 This definition of sequential composition is very useful concept for obtaining fractional derivative of ant arbitrary order. The derivative operator can be any definition RL or Caputo. 6 Kolwankar and Gangal (1994) Local fractional derivative is defined by Kolwankar and Gangal (KG) as to explain the behavior of ‘continuous but nowhere differentiable’ function. The other definition of fractional derivative in classical sense is integral-derivatives and is non-local property.
