The complexity of decision problems in automata theory and logic.
free download

The inherent computational complexity of a variety of decision problems in mathematical logic and the theory of automata is analyzed in terms of Turing machine time and space and in terms of the comp1exity of Boolean networks. The problem of deciding whether a star-free

This paper solves a problem of Arbib and Manes from the categorial automata theory : for which input processes F: K ~ K do minimal realizations always exist A generalization is exhibited, giving a model of finite automata and treating all functors, not only inputINTRODUCTION The concept of isolated cut-points plays a foundarnental role in the theory of probabilistic autornata. The following problern, suggested by ( 1 J and by [~] is qui te natural: (1) Can one device an algorithm to decide, for every given probabil_! stic autornaton The study of Process Algebra has received a great deal of attention since the pioneering work in the 1970s of the likes of R. Milner and CAR Hoare. This attention has been merited as the formalism provides a natural framework for describing and analysing systemsPage 1. FUZZY MORP~ISHMS IN AUTOMATA THEORY 1 M_.A.

Uniformization in automata theory
free download

We survey some classical results on uniformizations of automaton definable relations by automaton definable functions. We consider the case of automatic relations over finite and infinite words and trees as well as rational relations over finite and infinite words. We also

Real-time and complexity problems in automata theory

The note has three parts* In I, we give a sufficient condition for the existence of minimal realizations in 2tym,(T), F*% *, X(see [33) In II, we apply it to the case% as QZ and solve fully this situation* In III, we give a very simple sufficient condition for the existence of free F

The role of finite automata in the development of modern computing theory
free download

Absfract: Regular patterns described by finite automata are evident in the behavior of computers, in the structure of programming languages and in the rules for reasoning about programs. The systematic study of these patterns has shaped computing theory , providing

On some problems in the theory of partial automata
free download

The theory of automata is closely connected with the theory of semigroups (or, to be more exact, with the theory of representations of semigroups by transformations). The concept of automaton without outputs is equivalent to the concept of representa tion of free semigroup

In many process algebras, a nondeterministic choice in particular $mathrm {f}mathrm {o}mathrm {r}ln $ can be translated to a parallel composition with the expansion law. This translation, $mathrm {w}mathrm {h}mathrm {i}mathrm {c} 1_ {1} $ we will call par
