A Decidable Probability Logic for Timed Probabilistic Systems [PDF]

arXiv, 2004
In this paper we extend the predicate logic introduced in [Beauquier et al. 2002] in order to deal with Semi-Markov Processes. We prove that with respect to qualitative probabilistic properties, model checking is decidable for this logic applied to Semi-Markov Processes.

Infinite Dimensional Ito Algebras of Quantum White Noise [PDF]

Trends in Contemporary Infinite Dimensional Analysis and Quantum Probability 57--80, Instituto Italiano di Cultura, Kyoto, 2000, 2005
A simple axiomatic characterization of the general (infinite dimensional, noncommutative) Ito algebra is given and a pseudo-Euclidean fundamental representation for such algebra is described. The notion of Ito B*-algebra, generalizing the C*-algebra is defined to include the Banach infinite dimensional Ito algebras of quantum Brownian and quantum Levy ...

The Wild Number Problem: math or fiction? [PDF]

arXiv, 2012
In this article, I explain why I abandoned my original plan to write a novel about a mathematician proving Fermat's Last Theorem, letting my protagonist solve the entirely fictional Wild Number Problem instead. I enumerate the steps that had to be taken to make it seem as much like a genuine mathematical problem as possible.

Avrocar: a real flying saucer [PDF]

arXiv, 2015
One of the most unusual military aircraft programs V / STOL was the Avro VZ-9 "Avrocar". Designed to be a real flying saucer, the Avrocar was one of the few V / STOL to be developed in complete secrecy. Despite significant changes in the design, during flight tests, the Avrocar was unable to achieve its objectives, and the program was eventually ...

Variations on chaos in physics: from unpredictability to universal laws [PDF]

arXiv, 2016
The tremendous popular success of Chaos Theory shares some common points with the not less fortunate Relativity: they both rely on a misunderstanding. Indeed, ironically , the scientific meaning of these terms for mathematicians and physicists is quite opposite to the one most people have in mind and are attracted by.
