In this paper we propose two important extensions of the generalized prony. The simplest differential operator d acting on a function y, returns the first derivative of this function. Background although wave mechanics is capable of describing quantum behaviour of bound and unbound particles, some properties can not be represented this way, e. If d satisfies these laws, then it can be used as an algebraic operatoror a linear operator. Thus we can see that d does satisfy the laws of algebra very nearly except that it is not interchangeable with variables. The d operator differential calculus maths reference.
