Abstract. Permission-role assignment is an important issue in rolebased access control (RBAC). There are two types of problems that may arise in permission-role assignment. One is ...
We extend a previous type system for the -calculus that guarantees deadlock-freedom. The previous type systems for deadlockfreedom either lacked a reasonable type inference algorit...
We propose a characterization of PSPACE by means of a type assignment for an extension of lambda calculus with a conditional construction. The type assignment STAB is an extension...

Subtyping in first order object calculi is studied with respect to the logical semantics obtained by identifying terms that satisfy the same set of predicates, as formalised throu...
