Abstract

In this article we study bounded operators TT on Banach space XX which satisfy the discrete Gomilko Shi-Feng condition 02πR(reit,T)2x,xdtC(r21)\normex\normex,r>1,xX,xX.\int_{0}^{2\pi}|\langle R(re^{it},T)^{2}x,x^*\rangle |dt \leq \frac{C}{(r^2-1)}\norme{x}\norme{x^*},\quad r>1, x\in X, x^* \in X^*. We show that it is equivalent to a certain derivative bounded functional calculus and also to a bounded functional calculus relative to Besov space. Also on Hilbert space discrete Gomilko Shi-Feng condition is equivalent to power-boundedness. Finally we discuss the last equivalence on general Banach space involving the concept of γ\gamma-boundedness.
