Reachability and liveness in parametric timed automata [PDF]
We study timed systems in which some timing features are unknown parameters. Parametric timed automata (PTAs) are a classical formalism for such systems but for which most interesting problems are undecidable.

Analysis of cryptographic protocols using logics of belief: an overview
When designing a cryptographic protocol or explaining it, one often uses arguments such as ``since this message was signed by machine B, machine A can be sure it came from B`` in informal proofs justifying how the protocol works.

Modularity for decidability of deductive verification with applications to distributed systems
Proof automation can substantially increase productivity in formal verification of complex systems. However, unpredictablility of automated provers in handling quantified formulas presents a major hurdle to usability of these tools.

Decidability of Non-interactive Simulation of Joint Distributions [PDF]
We present decidability results for a sub-class of "non-interactive" simulation problems, a well-studied class of problems in information theory. A non-interactive simulation problem is specified by two distributions P(x, y) and Q(u, v): The goal is to ...

Decidability of the Membership Problem for 2 × 2 integer matrices [PDF]
The main result of this paper is the decidability of the membership problem for 2 × 2 nonsingular integer matrices. Namely, we will construct the first algorithm that for any nonsingular 2 × 2 integer matrices M1, . . .

Da metamatemática para a ciência cognitiva From metamathematics to Cognitive Science
Neste artigo, propõe-se uma configuração possível para a transição histórico-filosófica de temas investigados no domínio da metamatemática para o domínio da Ciência Cognitiva funcionalista neurocomputacional. A descrição de tal transição é feita por meio

Undecidable problems concerning densities of languages [PDF]
In this paper we prove that the question whether a language presented by a context free grammar has density, is undecidable. Moreover we show that there is no algorithm which, given two unambiguous context free grammars on input, decides whether the ...

Knowledge to Manage the Knowledge Society: The Concept of Theoretical Incompleteness
After having outlined the essential differences between non-complex systems and complex systems we briefly recall the conceptual approaches considered by the pre-complexity General Systems Theory introduced by Von Bertalanffy in 1968 and those of the ...
