### System I

Gilles Dowek and Alejandro Díaz-Caro have defined a lambda-calculus, the system I, to represent the proofs of a variant minimal propositional logic where isomorphic propositions are identified. Their paper Proof Normalisation in a Logic Identifying Isomorphic Propositions, has been presented at the International Conference on Formal Structures for Computation and Deduction. A second paper The virtues of eta-expansion in System I, showing that the addition of eta-expansion to system I actually simplies the system has been submitted to publication.
