Abstract

A Furstenberg family F\mathcal{F} is a collection of infinite subsets of the set of positive integers such that if ABA\subset B and AFA\in \mathcal{F}, then BFB\in \mathcal{F}. For a Furstenberg family F\mathcal{F}, finitely many operators T1,...,TNT_1,...,T_N acting on a common topological vector space XX are said to be disjoint F\mathcal{F}-transitive if for every non-empty open subsets U0,...,UNU_0,...,U_N of XX the set {nN: U0T1n(U1)...TNn(UN)}\{n\in \mathbb{N}:\ U_0 \cap T_1^{-n}(U_1)\cap...\cap T_N^{-n}(U_N)\neq\emptyset\} belongs to F\mathcal{F}. In this paper, depending on the topological properties of Ω\Omega, we characterize the disjoint F\mathcal{F}-transitivity of N2N\geq2 composition operators Cϕ1,,CϕNC_{\phi_1},\ldots,C_{\phi_N} acting on the space H(Ω)H(\Omega) of holomorphic maps on a domain ΩC\Omega\subset \mathbb{C} by establishing a necessary and sufficient condition in terms of their symbols ϕ1,...,ϕN\phi_1,...,\phi_N.
