Y1 - 2016/// N2 - The sharp estimates of the product of the inner radius for pairwise disjoint domains are obtained. In particular, we solve an extremal problem in the case of an arbitrary finite number of the free poles on the unit circle for the following functional PB - SciPress Ltd., Switzerland JF - International Journal of Advanced Research in Mathematics KW - inner radius of domain KW - quadratic differential KW - piecewise-separating transformation KW - Green function KW - radial systems of points KW - logarithmic capacity KW - variational formula SN - 2297-6213 TI - On the One Extremal Problem with the Free Poles on the Unit circle SP - 26 AV - public EP - 31 ER -
