Abstract:We provide in this paper a direct and constructive proof of the following fact: for a Banach space $X$ there are bounded linear operators having hypercyclic vectors if and only if $X$ is separable and dim$, X = infty $. This is a special case of a recent result, which in turn solves a problem proposed by S. Rolewicz.

Keywords:Hypercyclic vector   linear operator   infinite-dimensional separable Banach space   biorthogonal system   backward weighted shift
