Subtypes vs. Where Clauses: Constraining Parametric Polymorphism
All object-oriented languages provide support for subtype polymorphism, which allows the writing of generic code that works for families of related types. There is also a need, ho...

A Semantics of Object Types
: We give a semantics for a typed object calculus, an extension of System F with object subsumption and method override. We interpret the calculus in a per model, proving the sound...
