Truncated Dirichlet estimates for Bloch functions
Iason Efraimidis, Adrián Llinares, Alejandro Mas
We study the truncated Dirichlet functional \[ Φ_n (f) = \sum_{k = 1}^n k |a_k|^2, \quad f(z) = \sum_{k = 0}^\infty a_k z^k, \] when belongs to the Bloch space. If ,…
The norm of the backward shift on is
Konstantinos Bampouras, Adrián Llinares
We prove that the backward shift operator on has norm equal to , with . Furthermore, we characterize all extremal functions; they are pr…
classes in the Dirichlet range: inner-outer factorization, Carleson measures and weak products
Alberto Dayan, Adrián Llinares, Miguel Monsalve-López
We study properties of spaces in the Dirichlet range, recently defined by Brevig, Kulikov, Seip and Zlotnikov as the set of all holomorphic functions on the unit disc $\mat…
Critical exponents of the Riesz projection
Ole Fredrik Brevig, Adrián Llinares, Kristian Seip
Let denote the critical exponent of the Riesz projection from to the Hardy space , where is the unit circle.…
On the convolution of convex 2-gons
Martin Chuaqui, Rodrigo Hernández, Adrián Llinares +1
We study the convolution of functions of the form \[ f_α(z) := \dfrac{\left( \frac{1 + z}{1 - z} \right)^α- 1}{2 α}, \] which map the open unit disk of the complex plane onto polyg…
