The properties of the algebra H∞ of bounded holomorphic martingales are further studied following the work of N. Th. Varopoulos . The purpose of this paper is to discuss the behavior of weak* closed algebras B with H∞⫋ B ⫋ L∞and the support sets of H∞-functions. We also give some results on the factorization theorem for H∞and extreme points of the unit ball of H∞.
