We show how to implement a calculus with higher-order subtyping and subkinding by replacing uses of implicit subsumption with explicit coercions. To ensure this can be done, a pol...
We present a statically typed, class-based object oriented language where classes are first class polymorphic values. A main contribution of this work is the design of a type syst...
In [BCC00], we presented a general framework for extending calculi of mobile agents with object-oriented features, and we studied a typed instance of that model based on Cardelli a...
We present the design and rationale of a new statically-typed object-oriented language, LOOM. LOOM retains most of the features of the earlier language PolyTOIL. However the subtyp...
We compare Meyer and Routley's minimal relevant logic B+ with the recent semanticsbased approach to subtyping introduced by Frisch, Castagna and Benzaken in the definition of...
