Outers for noncommutative H^p revisited
David P. Blecher, Louis Labuschagne
We continue our study of outer elements of the noncommutative H^p spaces associated with Arveson's subdiagonal algebras. We extend our generalized inner-outer factorization theorem…

A Helson-Szegö theorem for subdiagonal subalgebras with applications to Toeplitz operators
Louis E Labuschagne, Quanhua Xu
We formulate and establish a noncommutative version of the well known Helson-Szego theorem about the angle between past and future for subdiagonal subalgebras. We then proceed to u…
