Isomorphic copies of ℓ1 for m‐homogeneous non‐analytic Bohnenblust–Hille polynomials
Abstract:We employ a classical result by Toeplitz (1913) and the seminal work by Bohnenblust and Hille on Dirichlet series (1931) to show that the set of continuous m‐homogeneous non‐analytic polynomials on c 0 contains an isomorphic copy of ?1. Moreover, we can have this copy of ?1 in such a way that every non‐zero element of it fails to be analytic at precisely the same point.
