The unbounded commutant of an operator of class C_0
, 2009 We describe the closed, densely defined linear transformations commuting with a given operator T of class C_0 in terms of bounded operators in {T}'.

On the double commutant expectation property for operator systems
, 2015 In this note we present an alternative viewpoint to the Double Commutant Expectation Property (DCEP) for operator systems, introduced by Kavruk, Paulsen, Todorov and Tomforde.

Commutant properties of w-core inverses
Kuwait Journal of ScienceIn this paper, we investigate commutant properties of the w-core inverse in a ∗-semigroup. Among these, it is shown that [Figure presented] if and only if a is equal projection (EP) with [Figure presented], where a and w are elements of a ∗-semigroup. As

The Vertex Algebra M(1)+ and Certain Affine Vertex Algebras of Level −1
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We give a coset realization of the vertex operatoralgebra $M(1)^+$ with central charge $ell$. We realize $M(1) ^+$as a commutant of certain affine vertex algebras of level $-1$ inthe vertex algebra $L_{C_{ell} ^{(1)}}(-frac{1}{2}Lambda_0)otimes L_{C_ ...

Symmetries as Ground States of Local Superoperators: Hydrodynamic Implications
PRX QuantumSymmetry algebras of quantum many-body systems with locality can be understood using commutant algebras, which are defined as algebras of operators that commute with a given set of local operators.

International Journal of Mathematics and Mathematical Sciences, 2012 Let R(𝔻) be the algebra generated in Sobolev space W22(𝔻) by the rational functions with poles outside the unit disk 𝔻¯. In this paper, we study the similarity invariant of the multiplication operators Mg in ℒ(R(𝔻)), when g is univalent analytic on 𝔻 or ...

, 2005 The category of von Neumann correspondences from B to C (or von Neumann B-C-modules) is dual to the category of von Neumann correspondences from C' to B' via a functor that generalizes naturally the functor that sends a von Neumann algebra to its ...
