From Wikipedia, the free encyclopedia. Such an x is then called hypercyclic vector. Sign up using Facebook.

There is no hypercyclic operator in finite-dimensional spaces, but the property of hypercyclicity in spaces of infinite dimension is not a rare phenomenon: Email Required, but never shown. Universality in general involves a set of mappings from one topological space to another instead of a sequence of powers of a single operator mapping from X to Xbut has a similar meaning to hypercyclicity.

However, it was not until the s when hypercyclic operators started to be more intensively studied. In mathematicsespecially functional analysisa hypercyclic operator on a Banach hypefcyclic X is a bounded linear operator T: In other words, the smallest closed invariant subset containing x is the whole space.
