An optimal estimate for extrapolation from a finite set in the Wiener class.
Let , be a domain with -boundary and be a compact set such that is connected. We study univalent analytic extension of CR-functions from to parts of . Call CR-convex if its -convex hull, , satisfies ( denoting the space of functions, which are holomorphic on and continuous up to ). The main theorem of the paper gives analytic extension to , if is CR- convex.
