Characterizations of noncommutative
David P. Blecher, Louis E. Labuschagne
We transfer a large part of the circle of theorems characterizing the generalization of classical known as `weak* Dirichlet algebras', to Arveson's noncommutative settin…

Pure state transformations induced by linear operators
Louis Labuschagne
We generalise Wigner's theorem to its most general form possible for B(h) in the sense of completely characterising those vector state transformations of B(h) that appear as restri…

Logmodularity and isometries of operator algebras
David P. Blecher, Louis E. Labuschagne
We generalize some facts about function algebras to operator algebras, using the `noncommutative Shilov boundary' or -envelope first considered by Arveson. In the first part w…
