Abstract. We show that for infinite transition systems induced by cryptographic protocols in the Rusinowitch/Turuani style certain fundamental branching properties are decidable. ...
Abstract. We address the problem of the density of intrinsically universal cellular automata among cellular automata or a subclass of cellular automata. We show that captive cellul...
Abstract. In this paper we determine some limit distributions of pattern statistics in rational stochastic models, defined by means of nondeterministic weighted finite automata. ...
