Abstract

Given a domain Ω\Omega in Cn\mathbb{C}^n and a collection of test functions Ψ\Psi on Ω\Omega, we consider the complex-valued Ψ\Psi-Schur-Agler class associated to the pair (Ω,Ψ)(\Omega,\,\Psi). In this article, we characterize interpolating sequences for the associated Banach algebra of which the Ψ\Psi-Schur-Agler class is the closed unit ball. When Ω\Omega is the unit disc D\mathbb{D} in the complex plane C\mathbb{C} and the class of test function includes only the identity function on D\mathbb{D}, the aforementioned algebra is the algebra of bounded holomorphic functions on D\mathbb{D} and in this case, our characterization reduces to the well known result by Carleson. Furthermore, we present several other cases of the pair (Ω,Ψ)(\Omega,\,\Psi), where our main result could be applied to characterize interpolating sequences which also show the efficacy of our main result.
