On the Hilbert space of Dirichlet series with square summable coefficients, we show that the linear combinations of two composition operators induced ......

We prove that L (SL2 (k)) is a maximal Haagerup-von Neumann subalgebra in L (k(2) (sic) SL2 (k)) for k = Q and k = Z. The key step for the proof is a ......

We compute the K-theory of crossed products of rotation algebras A(theta), for any real angle theta, by matrices in SL (2, Z) with infinite order. Usi......

This paper gives a systematic study of operator-valued local Hardy spaces, which are localizations of the Hardy spaces defined by Mei. We prove the h(......

In this paper, we discuss some equivalent definitions of Property Gamma for a type II1 von Neumann algebra. Using these equivalent definitions, we pro......

Let L-p(M) be the non-commutative L-p-space associated to a von Neumann algebra M with the canonical positive cone L-+(p)(M). Consider L-+(p)(M)(1-eps......

Motivated by reformulating Furstenberg's x p, x q conjecture via representations of a crossed product C*-algebra, we show that in a discrete C*-dynami......
