On the One Extremal Problem with the Free Poles on the Unit circle [PDF]

, 2016
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 ...

Blaschke products and Nevanlinna-Pick interpolation [PDF]

, 2015
For a Nevanlinna{Pick problem with more than one solution, Rolf Nevanlinna proved that all extremal solutions are inner functions. If the interpolation points are contained in dinitely many cones terminating at the unit circle, it is shown that all ...
