Abstract

top
Boundary values of zero-smooth Besov analytic functions in the unit ball of ℂ n are investigated. Bounded Besov functions with prescribed lower semicontinuous modulus are constructed. Correction theorems for continuous Besov functions are proved. An approximation problem on great circles is studied.
