Numerically hypercyclic polynomials

In this paper, we show that every complex Banach space X with dimension at least 2 supports a numerically hypercyclic d-homogeneous polynomial P for every ${d\in \mathbb{N}}$ . Moreover, if X is infinite-dimensional, then one can find hypercyclic non-homogeneous polynomials of arbitrary degree which are at the same time numerically hypercyclic. We prove that weighted shift polynomials cannot be numerically hypercyclic neither on c ₀ nor on ? _p for 1??? p?<???. In contrast, we characterize numerically hypercyclic weighted shift polynomials on ?_??.
