Splicing systems with marked rules.

Abstract

This paper deals with two types of results about splicing systems. First we try to give a new sufficient condition for a finite automaton to generate a splicing language, based on the structure of its transition graph. Second, the class of regular languages is characterized in terms of splicing systems where rules are marked at the leading or trailing end.
Both the results come from new insights about the relationships between the properties of (non extended) splicing systems, and finite state automata.
