On distributional point values and boundary values of analytic functions

Abstract

We give the following version of Fatou's theorem for distributions that are boundary values of analytic functions. We prove that if fD(a,b)f\in\mathcal{D}^{\prime}(a,b) is the distributional limit of the analytic function FF defined in a region of the form (a,b)×(0,R),(a,b) \times(0,R), if the one sided distributional limit exists, f(x0+0)=γ,f(x_{0}+0) =\gamma, and if ff is distributionally bounded at x=x0x=x_{0}, then the \L ojasiewicz point value exists, f(x0)=γf(x_{0})=\gamma distributionally, and in particular F(z)γF(z)\to \gamma as zx0z\to x_{0} in a non-tangential fashion.
