Abstract

We study a term assignment for an intuitonistic fragment of the Logic of Proofs (LP). LP is a refinement of modal logic S4 in which the assertion @?A is replaced by @?s@?A whose intended reading is ''s is a proof of A''. We first introduce a natural deduction presentation based on hypothetical judgements and then its term assignment, which yields a confluent and strongly normalising typed lambda calculus @l^I^H^L^P. This work is part of an ongoing effort towards reformulating LP in terms of hypothetical reasoning in order to explore its applications in programming languages.
