G- Cyclicity And Somewhere Dense Orbit
let H be an infinite – dimensional separable complex Hilbert space, and S be a multiplication semigroup of with 1. An operator T is called G-cyclic over S if there is a non-zero vector xÎ H such that {aTn x½aÎS, n ≥0} is norm-dense in H. Bourdon and Feldman have proved that the existence of somew...
