The Syntactic Complexity of Eulerian Graphs

  • Antonios Kalampakas
Part of the Lecture Notes in Computer Science book series (LNCS, volume 4728)


In this paper we prove that the set of directed Eulerian graphs is not recognizable. On the other hand, the set of directed graphs with an Eulerian underlying graph is shown to be recognizable. Furthermore, we compute the syntactic complexity of this language and we compare it with that of connected graphs.
