Correspondences between convex geometry and complex geometry [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2017
We present several analogies between convex geometry and the theory of holomorphic line bundles on smooth projective varieties or K\"ahler manifolds. We study the relation between positive products and mixed volumes.

Smale's mean value conjecture for finite Blaschke products [PDF]

open access: yes, 2016
Motivated by a dictionary between polynomials and finite Blaschke products, we study both Smale's mean value conjecture and its dual conjecture for finite Blaschke products in this paper.

Maximal Blaschke products

open access: yesAdvances in Mathematics, 2013
We consider the classical problem of maximizing the derivative at a fixed point over the set of all bounded analytic functions in the unit disk with prescribed critical points. We show that the extremal function is essentially unique and always an indestructible Blaschke product. This result extends the Nehari--Schwarz Lemma and leads to a new class of

Derivatives of Blaschke products [PDF]

open access: yesPacific Journal of Mathematics, 1984
This paper is a study of the behavior of the derivative of an infinite Blaschke product, focusing on membership of the derivative B' or fractional derivatives \(B^{\beta}\) in the classes \(A^{p,\alpha}\).

Blaschke inductive limits of uniform algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider and study Blaschke inductive limit algebrasA(b), defined as inductive limits of disc algebras A(D) linked by a sequence b={Bk}k=1∞ of finite Blaschke products.

Inner Functions in Lipschitz, Besov, and Sobolev Spaces

open access: yesAbstract and Applied Analysis, 2011
We study the membership of inner functions in Besov, Lipschitz, and Hardy-Sobolev spaces, finding conditions that enable an inner function to be in one of these spaces.

Pontryagin de Branges Rovnyak spaces of slice hyperholomorphic functions [PDF]

open access: yes, 2012
We study reproducing kernel Hilbert and Pontryagin spaces of slice hyperholomorphic functions which are analogs of the Hilbert spaces of analytic functions introduced by de Branges and Rovnyak.

Blaschke product generated covering surfaces [PDF]

open access: yesMathematica Bohemica, 2009
Summary: It is known that, under very general conditions, Blaschke products generate branched covering surfaces of the Riemann sphere. We are presenting here a method of finding fundamental domains of such coverings and we are studying the corresponding groups of covering transformations.

Maximal subalgebra of Douglas algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
When q is an interpolating Blaschke product, we find necessary and sufficient conditions for a subalgebra B of H∞[q¯] to be a maximal subalgebra in terms of the nonanalytic points of the noninvertible interpolating Blaschke products in B. If the set M(B)⋂
