Description
| - Podle známé věty ( Brown-Chevreau-Pearcy ) každá kontrakce na Hilbertově prostoru, jejíž spektrum obsahuje jednotkovou kružnici, má netriviální invariantní podprostor. Tj. existuje nenulový necyklický vektor. Zde je ukázáno, že každý operátor s ohraničenými mocninami, jehož spektrální poloměr je roven 1, má nenulový vektor, který není supercyklický. (cs)
- By the well-known result of Brown, Chevreau and Pearcy, every Hilbert space contraction with spectrum containing the unit circle has a nontrivial closed invariant subspace. Equivalently, there is a nonzero vector which is not cyclic. We show that each power bounded operator on a Hilbert space with spectral radius equal to one has a nonzero vector which is not supercyclic. Equivalently, the operator has a nontrivial closed invariant homogeneous subset.
