Majorization of the Modulus of Continuity of Analytic Functions

Abstract

Let \(G\) be an open set in the complex plane, \(f\) analytic in \(G\) and continuous in \(\overline G\). Let \(\mu\) is a majorant in the sense that \(\mu(t)\) is a nonnegative, nondecreasing function defined for \(t\geq 0\) with \(\mu(2t)\leq 2\mu(t)\) for all \(t\geq 0\) and \[ |f(z_1)- f(z_2)|\leq \mu(|z_1- z_2|)\tag{1} \] for \(z_1\) and \(z_2\) in \(\partial G\). It is known that in this case \[ |f(z_1)- f(z_2)|\leq C\mu(|z_1- z_2|)\tag{2} \] for \(z_1\) and \(z_2\) in \(\partial G\) with an absolute constant \(C\) for all \(z_1,z_2\in\overline G\) if \(G\) is simply connected or doubly connected. In this paper the author shows that such a result is true if \(G\) is an open set with only bounded components. It is also shown that if (1) holds for a fixed \(z_1\in \partial G\) and for all \(z_2\in\partial G\) then (2) holds for this \(z_1\) and for all \(z_2\in\overline G\). A survey of results of this type is also given.
