Підтримка:The author is grateful to Prof. Bakhtin for suggesting problems and useful discussions.
Sharp estimates of a product of inner radii for pairwise disjoint domains are obtained. In particular, the extremal problem in the case of any finite number of free poles at the points on rays is solved.
