Logical equivalence for subtyping object and recursive types.

Abstract
We study subtyping in first order object calculi with respect to the logical semantics obtained by identifying terms that satisfy the same set of predicates, as formalised through an assignment system. Equality in the full first order varsigma-calculus is modelled by this notion, which in turn is included in a Morris-style contextual equivalence.
Series This talk is part of the Logic and Semantics Seminar (Computer Laboratory) series.
