Abstract

In paper Molinelli et al, 1998 a general model allowing the integration of different kinds of calculus with diagrams appearing in several fields of Science and Engineering was introduced. And also, a computer aided system enabling some manipulation of this graphical stuff was presented. Traditionally most of these diagrams have been used as an aid in the development of complex calculus, although the lack of a solid theoretical foundation has prevent the existence of practical tools. As a contribution to that necessary background, we present here an implementation of the diagrams using Coq and a first discussion on the confluence of the rewriting based on the interchange law.
