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…

Jointly hyponormal pairs of commuting subnormal operators need not be jointly subnormal
Raul Curto, Jasang Yoon
We construct three different families of commuting pairs of subnormal operators, jointly hyponormal but not admitting commuting normal extensions. Each such family can be used to a…
