On Bloch seminorm of finite Blaschke products in the unit disk

چکیده
We prove that, for any finite Blaschke product w=B(z) in the unit disk, corresponding Riemann surface over w–plane contains a one-sheeted disk of radius 0.5. Moreover, it with radial slit. apply this result to obtain universal lower estimate Bloch seminorm products.

Boundary Interpolation by Finite Blaschke Products
Given 2n distinct points z1, z′ 1, z2, z ′ 2, . . . , zn, z ′ n (in this order) on the unit circle, and n points w1, . . . , wn on the unit circle, we show how to construct a Blaschke product B of degree n such that B(zj) = wj for all j and, in addition, B(z′ j) = B(z ′ k) for all j and k. Modifying this example yields a Blaschke product of degree n− 1 that interpolates the zj ’s to the wj ’s. ...
متن کاملThe Location of Critical Points of Finite Blaschke Products
A theorem of Bôcher and Grace states that the critical points of a cubic polynomial are the foci of an ellipse tangent to the sides of the triangle joining the zeros. A more general result of Siebert and others states that the critical points of a polynomial of degree N are the algebraic foci of a curve of class N − 1 which is tangent to the lines joining pairs of zeroes. We prove the analogous...
