Heaviside's fractional differentiator

Proceedings of the Physical Society, 1928
Operational methods involve the assumption that the operator may be treated whenever convenient either as an algebraic quantity or as the differentiator of the calculus. They are justified if theorems can be found to cover the processes actually used. Such theorems were simple and often obvious in the early methods of Boole and his immediate successors.

A fractional differential quadrature method for fractional differential equations and fractional eigenvalue problems

Mathematical Methods in the Applied Sciences, 2020
In this paper, based on the differential quadrature method (DQM), matrix operators are derived for fractional integration and Caputo differentiation. These operators generalize the efficient DQM to fractional calculus. The proposed fractional differential/integral quadrature method (FDIQM) is used to solve various types of fractional ordinary and ...

Total fractional differentials with applications to exact fractional differential equations

International Journal of Computer Mathematics, 2018
In this paper we introduce and study exact fractional differential equations, where we use the conformable fractional derivative. This forces us to introduce the fractional differential function.

Fractional Differential Equations

2018
Let the fractional differential equation (FDE) be $$\displaystyle (D^\alpha _{a_+}y)(t) = f[t,y(t)],\hspace {0.2 cm} \alpha > 0,\hspace {0.2 cm} t > a,$$ with the conditions: $$\displaystyle (D^{\alpha - k}_{a+}y)(a+) = b_k,\hspace {0.2 cm} k = 1,\ldots , n,$$ called also Riemann–Liouville FDE.
