Mikael Lindström

Welcome to my homepage. I am a Professor of Mathematics at Åbo Akademi University, Finland. Previously I was a Professor of Mathematics at the University of Oulu, Finland. I received my Ph.D. from Åbo Akademi University.

Research interests

Functional Analysis, Operator Theory and Complex Analysis. More precisely: Carleson type measures, integration operators, composition operators and Toeplitz operators on weighted Bergman spaces of infinite and finite order, essential norms and spectra of operators on various Banach spaces of analytic functions, homomorphisms on uniform algebras, interpolating sequences for analytic function spaces, duality problems for Banach spaces of analytic functions and invariant subspace problems.

Research group
