Abstract The class of ω-regular languages provide a robust specification language in verification. Every ω-regular condition can be decomposed into a safety part and a liveness...
We propose a new approach to the notion of recognition, which departs from the classical definitions by three specific features. First, it does not rely on automata. Secondly, it...
Formal power series are an extension of formal languages. Recognizable formal power series can be captured by the so-called weighted finite automata, generalizing finite state ma...
We propose an algorithm that tests membership for regular expressions and show that the algorithm is correct. This algorithm is written in the style of a sequent proof system. The...
A combinatorial channel is a set of pairs of words describing all the possible input-output channel situations. We introduce the concept "maximal error-detecting capability&q...
