We investigate the following lower bound methods for regular languages: The fooling set technique, the extended fooling set technique, and the biclique edge cover technique. It is ...
We introduce -synchronous relations for a rational number . We show that if a rational relation is both - and -synchronous for two different numbers and , then it is recognizab...
Bag context is a device for regulated rewriting in tree and string grammars. It represents context that is not part of the developing tree or string, but evolves on its own during ...

The paradigm of evolution/observation is based on the idea that a computing device can be obtained by combining a basic system and an observer that transforms the evolution of the ...

Abstract. We introduce the synchronization of a pushdown automaton by a sequential transducer associating an integer to each input word. The visibly pushdown automata are the autom...
A fragment of linear time temporal logic (LTL) is presented. It is proved that the satisfiability problem for this fragment is NPcomplete. The fragment is larger than previously kn...
Bottom-up tree series transducers (tst) over the semiring A are implemented with the help of bottom-up weighted tree automata (wta) over an extension of A. Therefore bottom-up D-w...
