$n$ -supercyclic and strongly $n$ -supercyclic operators in finite dimensions

Romuald Ernst

We prove that on $R^{n}$ , there is no $N$ -supercyclic operator with $1 \leq N < ⌊ \frac{n + 1}{2} ⌋$ i.e. if $R^{n}$ has an $N$ dimensional subspace whose orbi…

Strongly $n$ -supercyclic operators

Romuald Ernst

In this paper, we are interested in the properties of a new class of operators, recently introduced by Shkarin, called strongly $n$ -supercyclic operators. This notion is stronger t…
