Interpolation for a subclass of H ∞

We introduce and characterize two types of interpolating sequences in the unit disc \(\mathbb {D}\) of the complex plane for the class of all functions being the product of two analytic functions in \(\mathbb {D}\) , one bounded and another regular up to the boundary of \(\mathbb {D}\) , concretely in the Lipschitz class, and at least one of them vanishing at some point of \(\overline {\mathbb {D}}\) .
