Ergodic properties of operators in some semiHilbertian spaces
(2012) In Linear and Multilinear Algebra 61(2). p.139159 Abstract
 This article deals with linear operators T on a complex Hilbert space , which are bounded with respect to the seminorm induced by a positive operator A on . The Aadjoint and A 1/2adjoint of T are considered to obtain some ergodic conditions for T with respect to A. These operators are also employed to investigate the class of orthogonally mean ergodic operators as well as that of Apower bounded operators. Some classes of orthogonally mean ergodic or Aergodic operators, which come from the theory of generalized Toeplitz operators are considered. In particular, we give an example of an Aergodic operator (with an injective A) which is not Cesàro ergodic, such that T * is not a quasiaffine transform of an orthogonally mean ergodic... (More)
