ABSTRACT
Let $\mathcal{M}$ and $\mathcal{N}$ be the von Neumann algebras induced by the rational action of the group SL(â„) and its subgroup P on the upper half plane $\mathbb{H}$. We have shown that $\mathcal{N}$ is spatial isomorphic to the group von Neumann algebra $\mathcal{L}_P$ and characterized $\mathcal{M}$ and its commutant $\mathcal{M}'$ and gotten a generalization of the Mautner's lemma. It is also shown that the Berezin operator commutates with the Laplacian operator.

Extending the notion of property T of finite von Neumann algebras to general von Neumann algebras, we define and study in this paper property T** for (possibly non-unital) C*-algebras. We obtain several results of property T** parallel to those of property T for unital C*-algebras. Moreover, we...

Our goal is to prove the compactness of the difference between the thermoviscoelasticity semigroup and its decoupled semigroup. To show this, we prove the norm continuity of this difference, the compactness of the difference of their resolvents and useTheorem 2.3. We generalize a result by Liu....

This paper is devoted to the study of Jordan isomorphisms on nest subalgebras of factor von Neumann algebras. It is shown that every Jordan isomorphism Ï• between the two nest subalgebras algMÎ² and algMÎ³ is either an isomorphism or an anti-isomorphism.

We consider the Laplacian in a strip R (0,d) with the boundary condition which is Dirichlet except at the segment of a length 2a of one of the boundaries where it is switched to Neumann. This operator is known to have a non-empty and simple discrete spectrum for any a>0. There is a sequence...

We investigate the relationships between smooth and strongly smooth points of the unit ball of an order continuous symmetric function space E, and of the unit ball of the space of Ï„-measurable operators $${E(\mathcal{M},\tau)}$$ associated to a semifinite von Neumann algebra {(\mathcal{M},...
