Abstract We now return to the problem last mentioned in Chapter 2: how can we devise a model in which more information than that contained in single 100-base RNA molecules can be maintained over many generations? There are two main approaches that have been taken to this problem.

Frequently Hypercyclic Taylor Shifts
Computational Methods and Function Theory, 2016Let \(\mathbb {C}_{\infty}\) be the extended complex plane endowed with the spherical metric. Assume that \(\Omega\subset \mathbb {C}_{\infty}\) is an open set and \(0\in \Omega.\) Denote by \(H(\Omega)\) the set of holomorphic functions on \(\Omega\) (vanishing at infinity in case \(\infty \in \Omega\)) endowed with the topology of uniform convergence

We prove the existence of algebras of hypercyclic vectors in three cases: convolution operators, composition operators, and backward shift operators.
