Entailment of subtype constraints was introduced for constraint simplification in subtype inference systems. Designing an efficient algorithm for subtype entailment turned out to...

We investigate the first-order theory of subtyping constraints. We show that the first-order theory of nonstructural subtyping is undecidable, and we show that in the case where a...

Abstract. We study entailment of structural and nonstructural recursive subtyping constraints. Constraints are formal inequalities between type expressions, interpreted over an ord...

Abstract. Generic types in C behave invariantly with respect to subtyping. We propose a system of type-safe variance for C that supports the declaration of covariant and contravari...

Several kinds of call-ordering problems have been identified, all of which present subtle difficulties in ensuring the correctness of a sequential program. They include object pro...
