Subnormality of Powers of Multivariable Weighted Shifts
Given a pair T≡T1,T2 of commuting subnormal Hilbert space operators, the Lifting Problem for Commuting Subnormals (LPCS) asks for necessary and sufficient conditions for the existence of a commuting pair N≡N1,N2 of normal extensions of T1 and T2; in other words, T is a subnormal pair. The LPCS is a...
