Abstract
The present paper uses a game theoretic approach to make a fine study of the monadic theory of the infinite binary tree. We characterize some natural classes of monadic formulas in terms of alternating automata; in particular we give a hierarchy of automata corresponding to the hierarchy of alternation of quantifiers for weak monadic formulas. These characterizations lead to efficient decision procedures.
