Invariant Subspaces for Operators in a General II_1-factor
Uffe Haagerup, Hanne Schultz
It is shown that to every operator T in a general von Neumann factor M of type II_1 and to every Borel set B in the complex plane, one can associate a largest, closed, T-invariant…
On the best constants in noncommutative Khintchine-type inequalities
Uffe Haagerup, Magdalena Musat
We obtain new proofs with improved constants of the Khintchine-type inequality with matrix coefficients in two cases. The first case is the Pisier and Lust-Piquard noncommutative K…
Proper metrics on locally compact groups, and proper affine isometric actions on Banach spaces
Uffe Haagerup, Agata Przybyszewska
In this article it is proved, that every locally compact second countable group has a left invariant metric d, which generates the topology on G, and which is proper, ie. every clo…
Brown Measures of Unbounded Operators Affiliated with a Finite von Neumann Algebra
Uffe Haagerup, Hanne Schultz
In this paper we generalize Brown's spectral distribution measure to a large class of unbounded operators affiliated with a finite von Neumann algebra. Moreover, we compute the Bro…
