Bernhard B?schenstein,Ulrich Gaierhe framework of formal language theory. In spite of a vast literature on splicing systems, briefly surveyed here, a few problems related to their computational power are still open. We intend to evidence how classical techniques and concepts in automata theory are a legitimate tool for investigating some of these problems.

https://doi.org/10.1007/978-3-476-99053-2s. We prove that up to an initial part any natural number can occur as complexity of some language. Moreover, we show the existence of languages with small descriptional complexity with respect to one mechanism and large complexity with respect to the other device.
