L. creator: Targonskaya, I. subject: Математичний аналіз description: Sharp estimates of product of inner radii for pairwise disjoint domains are obtained. In particular, we solve an extremal problem in the case of arbitrary finite number of rays containing arbitrary even number of free poles publisher: SciPress Ltd., Switzerland date: 2016 type: Стаття type: PeerReviewed format: text language: uk identifier: http://eprints.zu.edu.ua/20629/1/IJARM.4.1.pdf identifier: Targonskii, A.
