Abstract:

A vector $x$ in a linear topological space $X$ is called universal for a linear operator $T$ on $X$ if the orbit $\{ {T^n}x:n \geq 0\}$ is dense in $X$. Our main result gives conditions on $T$ and $X$ which guarantee that $T$ will have universal vectors. It applies to the operators of differentiation and translation on the space of entire functions, where it makes contact with Pólya’s theory of final sets; and also to backward shifts and related operators on various Hilbert and Banach spaces.
