The Lengths of Proofs: Kreisel’s conjecture and Godel’s speed-up theorem
We collect and compare several results which have been obtained so far in the attempts to prove a statement conjectured by Kreisel, about the lengths of proofs. We also survey several results regarding a speed-up theorem announced by Goedel in an abstract published in 1936. Finally we connect this to Kreisel's conjecture. [preprint available in pdf]

Applications of Propositional Logic to Cellular Automata
In this paper we give a new proof of Richardson’s theorem : a global function G_{A} of a cellular automaton A is injective if and only if the inverse of G_{A} is a global function of a cellular automaton. More- over, we show a way how to construct the inverse cellular automaton using the method of feasible interpolation. We also solve two problems regarding complexity of cellular automata formulated by Bruno Durand.[preprint available in pdf]

The Conception of the Self in Multiple Cyber Worlds
In this paper we discuss many issues about personal identity and we propose a model of the Self in the Cyberspace based on information theory. This work combines some concepts from information theory, Dennett theory of multiple drafts with the concept of liminod as proposed by Victor Tucker in 1964.[preprint available in pdf]
