The Smirnov Class for Sub-Bergman Hilbert Spaces

Abstract

In this work we consider the Smirnov classes for sub-Bergman spaces. First we point out some observations about the Smirnov property of sub-Bergman space $H^\alpha(\varphi)$ and its relation to the defining $H^{\infty}_{1}$ function $\varphi$. The first main result of the work deals with the range of the defect operator over Smirnov-sub-Bergman class whereas in the last part we show that contrary to classical Bergman spaces, Smirnov-sub-Bergman classes have non-tangential boundary values almost everywhere on the unit circle.
