A study of ∇-discrete fractional calculus operator on the radial Schrodinger equation for some physical potentials

Abstract

The fractional calculus includes concepts of integrals and derivatives of any complex or real order. The fractional calculus is as old as the usual calculus. Recently, many scientists have been studying on this eld to provide the development and applicability to various areas of mathematics, physics, engineering and other sciences. The discrete fractional calculus has an important position in this eld. Some ordinary diffrential equations can be solved by means of nabla (∇) discrete fractional calculus operator. In this paper, we aim to apply this operator to the radial Schrodinger equation for some physical potentials such as pseudoharmonic and Mie-type potentials.
