Associated weights for spaces ofp-integrable entire functions

Abstract: In analogy to the notion of associated weights for weighted spaces of analytic functions with sup-norms, p-associated weights are introduced for spaces of entire p-integrable functions, 1 ≤ p < ∞. As an application, necessary conditions for the boundedness of composition operators acting between general Fock type spaces are proved. Notation and preliminariesConsider the space C N endowed with the complex inner product and the norm defined by:

“…We are interested in the study of the dynamics of C w,ϕ when the multiplier is of the type w(z) = p N (z)e βz , p N a polynomial of degree N , and β ∈ C. The next result (see [10,Proposition 5] and [19,Proposition 3.1]) yields that for such multipliers, in order to have the continuity of C w,ϕ we must reduce to affine symbols, i.e. symbols of the form ϕ(z) = az +b for some a, b ∈ C. Proposition 3.…”

“…In Section 3 we characterize the continuity and compactness of C w,ϕ on general weighted Banach spaces of entire functions, obtaining analogous results to those in [17] and [13] for the corresponding spaces on the disc and for unweighted composition operators, respectively. It is known (see [2,Corollary 30] and [14,Proposition 3.1]) that if the composition operator C ϕ on H vm (C) and on H 0 vm (C) is continuous, then the symbol ϕ must be affine, that is, ϕ(z) = az + b for some a, b ∈ C. In Proposition 6 we give a condition under which the continuity of the weighted composition operator also implies the affinity of the symbol. In Theorem 8 we characterize the continuity and compactness of C w,ϕ on H vm (C) and on H 0 vm (C) for affine symbols: In Section 4 we study the spectrum of the composition operator and the power boundedness, (uniform) mean ergodicity and hypercyclicity of C w,ϕ on the spaces H vm (C) and H 0 vm (C) when ϕ(z) = az + b.…”
