Abstract
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 between k-hyponormality and ( k + 1 ) -hyponormality for each k ⩾ 1 . As a consequence, we obtain an abstract solution to the Lifting Problem for Commuting Subnormals.
