We show that the first-order theory of structural subtyping of non-recursive types is decidable, as a consequence of a more general result on the decidability of term powers of d...

We establish the eventual periodicity of the spectrum of any monadic second-order formula where (i) all relation symbols, except equality, are unary, and (ii) there is only one fu...

We consider instantiation-based theorem proving whereby instances of clauses are generated by certain inferences, and where inconsistency is detected by propositional tests. We gi...

This paper reports on and discusses three notions of approximation for Labelled Markov Processes that have been developed last year. The three schemes are improvements over former...

We present decidability results for the verification of cryptographic protocols in the presence of equational theories corresponding to xor and Abelian groups. Since the perfect ...

We provide a method for deciding the insecurity of cryptographic protocols in presence of the standard Dolev-Yao intruder (with a finite number of sessions) extended with so-call...

In this paper, we develop a new substructural logic that can encode invariants necessary for reasoning about hierarchical storage. We show how the logic can be used to describe th...
