Extreme Points and Factorizability for New Classes of Unital Quantum Channels
Uffe Haagerup, Magdalena Musat, Mary Beth Ruskai
We introduce and study two new classes of unital quantum channels. The first class describes a 2-parameter family of channels given by completely positive (CP) maps $M_3({\bf C}) \…
Structure of bicentralizer algebras and inclusions of type III factors
Hiroshi Ando, Uffe Haagerup, Cyril Houdayer +1
We investigate the structure of the relative bicentralizer algebra for inclusions of von Neumann algebras with normal expectation where is a type ${\r…
Computational explorations of the Thompson group T for the amenability problem of F
S. Haagerup, U. Haagerup, M. Ramirez-Solano
It is a long standing open problem whether the Thompson group is an amenable group. In this paper we show that if , , denote the standard generators of Thompson group…
Non-inner amenability of the Thompson groups T and V
Uffe Haagerup, Kristian Knudsen Olesen
In this paper we prove that the Thompson groups and are not inner amenable. In particular, their group von Neumann algebras do not have property . Moreover, we prove tha…
On the uniqueness of injective III factor
Uffe Haagerup
We give a new proof of a theorem due to Alain Connes, that an injective factor of type III with separable predual and with trivial bicentralizer is isomorphic to the Araki-…
Group C*-algebras without the completely bounded approximation property
Uffe Haagerup
It is proved that: (1) The Fourier algebra A(G) of a simple Lie group G of real rank at least 2 with finite center does not have a multiplier bounded approximate unit. (2) The redu…
