Matrix-weighted little BMO spaces in two parameters

Spyridon Kakaroumpas, Odí Soler i Gibert

In this paper we set up a theory of two-matrix weighted little BMO in two parameters. We prove that being a member of this class is equivalent to belonging uniformly in each variab…

Preimages under linear combinations of iterates of finite Blaschke products

Spyridon Kakaroumpas, Odí Soler i Gibert

Consider a finite Blaschke product $f$ with $f (0) = 0$ which is not a rotation and denote by $f^{n}$ its $n$ -th iterate. Given a sequence ${a_{n}}$ of complex numbers, consider the s…
