archivesA Model for Formal Parametric Polymorphism: A PER Interpretation for System RA Model for Formal Parametric Polymorphism: A PER Interpretation for System R , Roberto Bellucci, Martin Abadi, Pierre-Louis Curien. TLCA 1995
System R is a logic for proving relational parametricity results. It's similar in some ways to Abadi-Plotkin logic, which we have linked to previously on LtU. Cyclic Proofs for First-Order Logic with Inductive DefinitionsCyclic Proofs for First-Order Logic with Inductive Definitions, James Brotherston, in Proceedings of TABLEAUX 2005
This technique of making potentially cyclic proof-graphs is really nice since it makes the connection between recursive definitions in a functional programming language and a proof structure very obvious. There is no need to specify the inductive principle ahead of time, you can simply structure the proof tree as you would your functional code.
