A Random Matrix Approach to the Lack of Projections in C*_red(F_2)

Uffe Haagerup, Hanne Schultz, Steen Thorbjornsen

In 1982 Pimsner and Voiculescu computed the K_0- and K_1-groups of the reduced group C*-algebra C*_red(F_k) of the free group F_k on k generators and settled thereby a long standin…

Moment Formulas For The Quasi-Nilpotent DT-Operator

L. Aagaard, U. Haagerup

Let T be the quasi-nilpotent DT-operator. By use of Voiculescu's amalgamated R-transform we compute the moments of $(T - λ 1)^{*} (T - λ 1)$ , where $λ \in C$ , and the Brown-measure o…
