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