Abstract:

In this paper we study the cyclic properties of the infinite continuous Cesàro operator defined on $L^2(0,\infty )$ by $(C_\infty f)(x)=\frac {1}{x}\int _0^x f(s) ds$. Despite this operator being cyclic, we show that it is not supercyclic; even more, it is not weakly supercyclic. These results complement some recent ones on the cyclic behavior of Cesàro operators.
