## Research groups

Mathematics in Åbo Akademi is actively engaged in high level research in functional analysis, stochastics, and applied mathematics.

**Functional Analysis**

The two main themes in the functional analysis group are the study of the structure of function spaces, and mathematical systems theory with applications to control theory and mathematical physics.

- Function Spaces and Operator Theory
- Mathematical Systems Theory

**Stochastics and Applied Mathematics**

The research objectives of the group are the development of mathematical theories and analysis of models coming from problems in other sciences as well as other branches of mathematics.

- Stochastics
- Numerical Analysis and Applied Mathematics

## Researchers

**Christer Glader**, University Teacher in Mathematics, Docent

Research profile and publications

**Research interests:
**My field of interest is approximation theory in the complex domain, particularly constructive methods for approximation and interpolation by finite Blaschke products.

**Mikael Kurula**, Senior Lecturer in Mathematics, Docent in Applied Mathematics. Webpage: http://users.abo.fi/mkurula/

Reseach profile and publications

**Research interests:
**I research systems and control theory, mostly in the context of infinite-dimensional linear systems described by partial differential equations. At the time being, I am particularly interested in model-predictive control of passive boundary control/boundary observation systems

**Mikael Lindström**, Professor in Mathematics, Head of Subject

Research profile and publications

**Research interests:
**My research is in the area of functional analysis, operator theory and complex analysis. More precisely, I am working with various Banach spaces of analytic functions, including weighted Bergman spaces and weighted Banach spaces of analytic functions and operators defined between them, particularly with the Hilbert matrix operator, weighted composition operators and integration operators. Other research topics concern interpolating sequences for analytic function spaces and invariant subspace problems.
