Towards a non-selfadjoint version of Kadison’s theorem [PDF]

Kadison’s theorem of 1951 describes the unital surjective isometries be- tween unital C*-algebras as the Jordan *-isomorphisms. We propose a nonselfadjoint version of his theorem and discuss the cases in which this is known to be true.

Strong Singularity For Subalgebras Of Finite Factors

, 2008
In this paper we develop the theory of strongly singular subalgebras of von Neumann algebras, begun in earlier work. We mainly examine the situation of type II 1 factors arising from countable discrete groups.

Weakly almost periodic functionals on certain Banach algebras

, 2017
For a Lau algebra A, we study the Banach space WAP(A) of all weakly almost periodic functionals on A to obtain some equivalent conditions for the exis-tence of topological left invariant means on a topological left introverted subspace X of A contained ...

NORMALIZERS OF IRREDUCIBLE SUBFACTORS

, 2008
We consider normalizers of an irreducible inclusion N ⊆ M of II1 factors. In the infinite index setting an inclusion uNu ∗ ⊆ N can be strict, forcing us to also investigate the semigroup of one-sided normalizers. We relate these normalizers of N in M to

, 2015
In this paper, the author proves an asymptotic version of the double commutant theorem, in a particular set-up of commutative C∗ -algebras. More precisely, he considers the relative approximate double commutant of a C ∗-algebra with unit, and, using a
