Unifying lower bounds for algebraic machines, semantically
Thomas Seiller, Luc Pellissier, Ulysse Léchine
This paper presents a new abstract method for proving lower bounds in computational complexity. Based on the notion of topological and measurable entropy for dynamical systems, it…
Undecidable word problem in subshift automorphism groups
Pierre Guillon, Emmanuel Jeandel, Jarkko Kari +1
This article studies the complexity of the word problem in groups of automorphisms of subshifts. We show in particular that for any Turing degree, there exists a subshift whose aut…
Slopes of 3-dimensional Subshifts of Finite Type
Etienne Moutot, Pascal Vanier
In this paper we study the directions of periodicity of three-dimensional subshifts of finite type (SFTs) and in particular their slopes. A configuration of a subshift has a slope…
Aperiodic points in -subshifts
Anael Grandjean, Benjamin Hellouin de Menibus, Pascal Vanier
We consider the structure of aperiodic points in -subshifts, and in particular the positions at which they fail to be periodic. We prove that if a -subshi…
Proceedings Joint Workshop on Handling IMPlicit and EXplicit knowledge in formal system development (IMPEX) and Formal and Model-Driven Techniques for Developing Trustworthy Systems (FM&MDD)
Régine Laleau, Dominique Méry, Shin Nakajima +1
This volume contains the joint proceedings of IMPEX 2017, the first workshop on Handling IMPlicit and EXplicit knowledge in formal system development and FM&MDD, the second worksho…
