The LR parser generators that are bundled with many functional programming language implementations produce code that is untyped, needlessly inefficient, or both. We show that, us...
In previous work we have developed a syntactic reduction of repeated reachability to reachability for finite state systems. This may lead to simpler and more uniform proofs for mo...
We present a proof technique in -calculus that can facilitate inductive reasoning on -terms by separating certain -developments from other -reductions. We give proofs based on thi...
The AVISPA Tool is a push-button tool for the Automated Validation of Internet Security Protocols and Applications. It provides a modular and expressive formal language for specif...
In general, invariants may depend on the state of other objects. The approach introduced in this paper allows this for objects of mutually visible classes, in a way that supports ...
