Hypercyclic transform of operators
Let be a bounded operator on some Hilbert space and be its Aluthge transform. and share in general their spectral properties and have been intensively treated this last decade. In our talk the cyclic behaviour is investigated. We show that adjoints have he same cyclic behaviour. This is done through some commutation techniques.
