Abstract:
Abstract In this note, we point out that a large family of n×n matrix valued kernel functions defined on the unit disc $$ \mathbb{D} \subseteq \mathbb{C} $$ , which were constructed recently in [9], behave like the familiar Bergman kernel function on $$ \mathbb{D} $$ in several different ways. We show that a number of questions involving the multiplication operator on the corresponding Hilbert space of holomorphic functions on $$ \mathbb{D} $$ can be answered using this likeness.
