Abstract

A bounded linear operator TT acting on a Hilbert space H\mathcal{H} is said to be recurrent if for every non-empty open subset UHU\subset \mathcal{H} there is an integer nn such that Tn(U)UT^n (U)\cap U\neq\emptyset. In this paper, we completely characterize the recurrence of scalar multiples of composition operators, induced by linear fractional self maps of the unit disk, acting on weighted Dirichlet spaces SνS_\nu; in particular on the Bergman space, the Hardy space, and the Dirichlet space. Consequently, we complete a previous work of Costakis et al. \cite{costakis} on recurrence of linear fractional composition operators on Hardy space. In this manner, we determine the triples (λ,ν,ϕ)C×R×LFM(D)(\lambda,\nu,\phi)\in \mathbb{C}\times \mathbb{R}\times LFM(\mathbb{D}) for which the scalar multiple of composition operator λCϕ\lambda C_\phi acting on SνS_\nu fails to be recurrent.
