Interpolation in the Nevanlinna class and harmonic majorants
A. Hartmann, X. Massaneda, A. Nicolau +1
We consider a free interpolation problem in Nevanlinna and Smirnov classes and find a characterization of the corresponding interpolating sequences in terms of the existence of har…
Harmonic and superharmonic majorants on the disk
Alexander Borichev, Artur Nicolau, Pascal J. Thomas
We prove that a positive function on the unit disk admits a harmonic majorant if and only if a certain logarithmic Lipschitz upper envelope of it (relevant because of the Harnack i…
The constant of interpolation
Artur Nicolau, Joaquim Ortega-Cerdà, Kristian Seip
We prove that a suitably adjusted version of Peter Jones' formula for interpolation by bounded holomorphic functions gives a sharp upper bound for what is known as the constant of…
