A new class of languages of infinite words is introduced, called the min-regular languages, extending the class of omega-regular languages. Min-regular languages are somehow dual to max-regular languages introduced before. The class has two equivalent descriptions: in terms of automata (a type of deterministic counter automaton), and in terms of logic (weak monadic second-order logic with a bounding quantifier).
