Abstract

In this paper, we show that for a wide class of operators T--including infinite order differential operators, and multiplication and composition operators--acting on the space H(D) of holomorphic functions in the unit disk D, we have most functions f ∈ H(D) which enjoy the property that T f has maximal radial cluster set at any boundary point.
