Weakly recognizing morphisms from free semigroups onto finite semigroups are a classical way for defining the class of $$\omega$$-regular languages, i.e., a set of infinite words is weakly recognizable by such a morphism if and only if it is accepted by some Buchi automaton. We consider the descriptional complexity of various constructions for weakly recognizing morphisms. This includes the conversion from and to Buchi automata, the conversion into strongly recognizing morphisms, and… Expand

This paper suggests first considering the class of full automata in lower bound analysis, and later reducing the size of the large alphabet via alphabet substitutions, and applies such technique to the complementation of nondeterministic \omega-automata, and gets several lower bound results. Expand

The syntactic congruence of L is defined, which is the largest congruences having this property, and it is shown that if L is a rational ω-language, then there exists a finite congruency for which L is saturated in the following sense. Expand

Abstract We study upper bounds on the size of the semigroups generated two randomly chosen n × n Boolean matrices having exactly N one entries. In general, as N n increases the semigroups tend to beExpand
A proof of Devadze’s theorem on generators of the semigroup of Boolean matrices
In 1968 Devadze described, without a proof, minimal sets of generators of the semigroup of n×n Boolean matrices. We provide a proof of Devadze’s theorem.
