Engel: A Mathematica Implementation of q-Engel Expansion

This package is part of the RISCErgoSum bundle. See Download and Installation.

Short Description

Engel is a Mathematica implementation of the q -Engel Expansion algorithm which expands q-series into inverse polynomial series. Examples of q-Engel Expansions include the Rogers-Ramanujan identities together with their elegant generalization by Garrett, Ismail and Stanton.
