Reconstruction of the Berger measure when the core is of tensor form

Raul E. Curto, Sang Hoon Lee, Jasang Yoon

Let denote the class of commuting pairs of subnormal operators on Hilbert space, and let $\mathcal{TC}:=\{\mathbf{T}\in \mathfrak{% H}_{0}:c(\mathbf{T)}$ is of t…

k-hyponormality of multivariable weighted shifts

Raul E. Curto, Sang Hoon Lee, Jasang Yoon

We characterize joint k-hyponormality for 2-variable weighted shifts. Using this characterization we construct a family of examples which establishes and illustrates the gap betwee…
