Generalized Toeplitz operators and cyclic vectors

We give in this paper some asymptotic Von Neumann inequalities for power bounded operators in the class C subrho intersection C sub 1. and some spacial von Neumann inequalities associated with non zero elements of the point spectrum, when it is non void, of generalized Toeplitz operators.
