| Abstract: | The concept of backward extension for subnormal weighted shifts is generalized to arbitrary subnormal operators. Several differences and similarities in these contexts are explored, with emphasis on the structure of the underlying measures. |
| Keywords: | Cyclic vectors subnormal operators moment measures |
