Contractions without non-trivial invariant subspaces satisfying a positivity condition
Abstract An operator A ∈ B ( H ) $A\in B(\mathcal{H})$ , the algebra of bounded linear transformations on a complex infinite dimensional Hilbert space H $\mathcal{H}$ , belongs to class A ( n ) $\mathcal{A}(n)$ (resp., A ( ∗ − n ) $\mathcal{A}(*-n)$ ) if | A | 2 ≤ | A n + 1 | 2 n + 1 $\vert A\vert^{...
