Abstract

Let DD be the differentiation operator Df=fDf=f' acting on the Fr\'echet space \H of all entire functions in one variable with the standard (compact-open) topology. It is known since 1950's that the set H(D)H(D) of hypercyclic vectors for the operator DD is non-empty. We treat two questions raised by Aron, Conejero, Peris and Seoane-Sep\'ulveda whether the set H(D)H(D) contains (up to the zero function) a non-trivial subalgebra of \H or an infinite dimensional closed linear subspace of \H. In the present article both questions are answered affirmatively.
