Constructions of some families of smooth Cauchy transforms

Adem Limani, Bartosz Malman

For a given Beurling-Carleson subset of the unit circle which has positive Lebesgue measure, we give explicit formulas for measurable functions supported on su…

Inner functions, invariant subspaces and cyclicity in -spaces

Adem Limani, Bartosz Malman

We study the invariant subspaces generated by inner functions for a class of -spaces which can be identified as spaces of analytic functions in the unit disk $\ma…

On the problem of smooth approximations in de Branges-Rovnyak spaces and connections to subnormal operators

Adem Limani, Bartosz Malman

For the class of de Branges-Rovnyak spaces of the unit disk defined by extreme points of the unit ball of , we study the problem of appr…

An abstract approach to approximations in spaces of pseudocontinuable functions

Adem Limani, Bartosz Malman

We give an abstract approach to approximations with a wide range of regularity classes in spaces of pseudocontinuable functions , where is an inner f…

Sparse Lerner operators in infinite dimensions

Adem Limani, Sandra Pott

We use the principle of almost orthogonality to give a new and simple proof that a sparse Lerner operator is bounded on a matrix- or operator-weighted space , where …

On model spaces and density of functions smooth on the boundary

Adem Limani, Bartosz Malman

We characterize the model spaces in which functions with smooth boundary extensions are dense. It is shown that such approximations are possible if and only if the singular m…
