Words, Languages And Combinatorics - Proceedings Of The International Conference

"For mathematicians interested in Algebra and its relationship with Computer Science the articles will offer an impressive view into the mainstreams of the current research. For the semigroup theorist they will give the convincing confirmation that his theory is something useful, which can be applied in other disciplines receiving conversely new ideas, new tasks and new impulses for its further development." H Mitsch, Wien Monatshefte fur Mathematik, 1993
