Abstract. The calculus of structures is a framework for specifying logical systems, which is similar to the one-sided sequent calculus but more general. We present a system of infe...
This paper presents a formal model and a systematic approach to the validation of communication tures at a high level of abstraction. This model is described mathematically by a fu...
In this paper we prove tight bounds on the combinatorial and topological complexity of sets defined in terms of n definable sets belonging to some fixed definable family of sets i...
The most studied property, secrecy, is not always sufficient to prove the security of a protocol. Other properties such as anonymity, privacy or opacity could be useful. Here, we u...
: It is well known that, in a topological space, the open sets can be characterized using filter convergence. In ZF (Zermelo-Fraenkel set theory without the Axiom of Choice), we c...
