Operators commuting with complex symmetric weighted composition operators on H 2
Concrete OperatorsIn this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

All solutions to the relaxed commutant lifting problem
, 2005 A new description is given of all solutions to the relaxed commutant lifting problem. The method of proof is also different from earlier ones, and uses only an operator-valued version of a classical lemma on harmonic majorants.Comment: 15 ...

On commuting and semi-commuting positive operators [PDF]
Proceedings of the American Mathematical Society, 2014 Let K K be a positive compact operator on a Banach lattice. We prove that if either [ K ⟩ [K\rangle or ⟨ K ] \langle K] is ideal irreducible, then [ K ⟩ = ⟨ K ] = L +

Behind-the-horizon excitations from a single 2d CFT
Journal of High Energy PhysicsIn this work, we consider the atypical non-equilibrium state found in [1708.06328] which holographically represents a behind-the-horizon excitation in a black hole spacetime.

Covariant representations for matrix-valued transfer operators
, 2007 Motivated by the multivariate wavelet theory, and by the spectral theory of transfer operators, we construct an abstract affine structure and a multiresolution associated to a matrix-valued weight.

Three Ways to Representations of B^a(E)
, 2004 We describe three methods to determine the structure of (sufficiently continuous) representations of the algebra B^a(E) of all adjointable operators on a Hilbert B-module E by operators on a Hilbert C-module. While the last and latest proof is simple and

Holography and localization of information in quantum gravity
Journal of High Energy PhysicsWithin the AdS/CFT correspondence, we identify a class of CFT operators which represent diff-invariant and approximately local observables in the gravitational dual.
