SUBNORMALITY AND OPERATOR MULTIDIMENSIONAL MOMENT PROBLEMS
Published online by Cambridge University Press: 06 April 2005
Abstract
Characterizations of subnormality due to Trent are extended to finite systems of operators, thus generalizing results of Gãvruţã and Suciu (subnormal pairs) and Binzar and Pãunescu (subnormal triplets). Vector and operator multidimensional moment problems with jointly subnormal solutions are characterized entirely in terms of the initial data. Bounded as well as unbounded solutions are taken into consideration.
