This paper studies specific language level abstractions for component-based programming. We propose a simple model which captures some basic ingredients — like explicit context ...
Programs are often structured around the idea that different pieces of code comprise distinct principals, each with a view of its environment. Typical examples include the module...

This paper gives the first proof that the subtyping relation of a higherorder lambda calculus, Fω ≤, is anti-symmetric, establishing in the process that the subtyping relation...
The problem of defining and checking a subtype relation between recursive types was studied in [3] for a first order type system, but for second order systems, which combine subty...
Abstract. We define sequent-style calculi for nominal tense logics characterized by classes of modal frames that are first-order definable by certain Π0 1 -formulae and Π0 2 -...
