Dependently-Typed Formalisation of Typed Term Graphs
Wolfram Kahl · Electronic Proceedings in Theoretical Computer Science · 2011
We employ the dependently-typed programming language Agda2 to explore formalisation of untyped and typed term graphs directly as set-based graph structures, via the gs-monoidal categories of Corradini and Gadducci, and as nested let-expressions using Pouillard and Pottier's NotSoFresh library of variable-binding abstractions.
