✦ Synopsis


We show that the independence relation defining a trace monoid M admits a transitive orientation if and only if the characteristic series ~ of a lexicographic cross section of M is the inverse of the determinant of (Id-X), where X is a matrix representing the minimum finite automaton recognizing ~ and Id is the identity matrix. This implies that, if the independence relation of a trace monoid M admits a transitive orientation, then any unambiguous lifting of the M6bius function of M is the determinant of a matrix defined by the smallest acceptor of the corresponding cross section.

For p # (0, 1), let Q p (Q p, 0 ) be the space of analytic functions f on the unit disk , where &} & D p means the weighted Dirichlet norm and . w is the Mo bius map of 2 onto itself with . w (0)=w. In this paper, we prove the Corona theorem for the algebra then we provide a Fefferman Stein type d
