Multiplication by Blaschke products and stability of ideals in Lipschitz algebras.
Absolute values of BMOA functions.
The paper contains a complete characterization of the moduli of BMOA functions. These are described explicitly by a certain Muckenhoupt-type condition involving Poisson integrals. As a consequence, it is shown that an outer function with BMO modulus need not belong to BMOA. Some related results are obtained for the Bloch space.
