This is a book about a beautiful subject that begins with the topic of Möbius transformations.
Indeed, Möbius transformations z↦→ az+ b cz+ d are studied in complex analysis since their …

We prove the necessity and sufficiency of the generalized Carleson condition (CG) for free
interpolation in the Hardy spaces Hp, 1< p≤∞, by identifying scalar operator interpolation …

The approximation properties of simplest fractions (sf's), that is, of the logarithmic derivatives
of complex polynomials, have recently become a subject of intensive research. These …
