Abstract
In this paper we give a proof that it is decidable for a deterministic tree automaton on infinite trees with Rabin acceptance condition, if there exists an equivalent nondeterministic automaton with Büchi acceptance condition. In order to prove this we transform an arbitrary deterministic Rabin automaton to a certain canonical form. Using this canonical form we are able to say if there exists a Büchi automaton equivalent to the initial one. Moreover, if it is the case, the canonical form allows us also to find a respective Büchi automaton.
