On the predual of non-commutative $H^\infty$

Abstract

The unique predual $M_\star/A_\perp$ of a non-commutative $H^\infty$-algebra $A = H^\infty(M,\tau)$ is investigated. In particular, we will prove the liftability property of weakly relatively compact subsets in $M_\star/A_\perp$ to $M_\star$.Comment: 10 pages, Final version, to appear in BLM
