Abstract

The class of ω-languages recognized by systolic tree automata is introduced. That class extends the class of Büchi ω-languages and is closed under boolean operations. The emptiness problem for systolic tree automata on infinite sequences is decidable. A characterization of systolic tree ω-languages in terms of a (suitable) concatenation of (finitary) systolic tree languages is also provided.
