Turing degrees of limit sets of cellular automata
Alex Borello, Julien Cervelle, Pascal Vanier
Cellular automata are discrete dynamical systems and a model of computation. The limit set of a cellular automaton consists of the configurations having an infinite sequence of pre…
Small Universal Petri Nets with Inhibitor Arcs
Sergiu Ivanov, Elisabeth Pelz, Sergey Verlan
We investigate the problem of construction of small-size universal Petri nets with inhibitor arcs. We consider four descriptional complexity parameters: the number of places, trans…
Finite-type-Dyck shift spaces
Marie-Pierre Béal, Michel Blockelet, Cǎtǎlin Dima
We study some basic properties of sofic-Dyck shifts and finite-type-Dyck shifts. We prove that the class of sofic-Dyck shifts is stable under proper conjugacies. We prove a Decompo…
One-dimensional Array Grammars and P Systems with Array Insertion and Deletion Rules
Rudolf Freund, Sergiu Ivanov, Marion Oswald +1
We consider the (one-dimensional) array counterpart of contextual as well as insertion and deletion string grammars and consider the operations of array insertion and deletion in a…
Sofic-Dyck shifts
Marie-Pierre Béal, Michel Blockelet, Cǎtǎlin Dima
We define the class of sofic-Dyck shifts which extends the class of Markov-Dyck shifts introduced by Inoue, Krieger and Matsumoto. Sofic-Dyck shifts are shifts of sequences whose f…
Random Context and Semi-Conditional Insertion-Deletion Systems
Sergiu Ivanov, Sergey Verlan
In this article we introduce the operations of insertion and deletion working in a random-context and semi-conditional manner. We show that the conditional use of rules strictly in…
