First Baire class functions in the pluri-fine topology

General Topology 2015-10-09 v3

Abstract

Let B1(Ω,R)B_{1}(\Omega, \mathbb R) be the first Baire class of real functions in the pluri-fine topology on an open set ΩCn\Omega \subseteq \mathbb C^{n} and let H1(Ω,R)H_{1}^{*}(\Omega, \mathbb R) be the first functional Lebesgue class of real functions in the same topology. We prove the equality B1(Ω,R)=H1(Ω,R)B_{1}(\Omega, \mathbb R)=H_{1}^{*}(\Omega, \mathbb R) and show that for every fB1(Ω,R)f\in B_{1}(\Omega, \mathbb R) there is a separately continuous function g:Ω2Rg: \Omega^{2} \to\mathbb R in the pluri-fine topology on Ω2\Omega^2 such that ff is the diagonal of g.g.
