This research group started its work during the fall of 2002. Our initial aim was to study non-linear potential theory in variable exponent Sobolev spaces. Since this was uncharted territory with several interesting applications. We have expanded our research to generalised Orlicz spaces, minimizers and partial differential equations with non-standart growth conditions, and to image restoration.

The group studies combinatorial and algebraic coding theory as well as graph theory. In particular, the main topics include identifying codes, information retrieval and space-time codes.
Group leaders: Iiro Honkala (Professor), Tero Laihonen (Professor)
Group members: Anni Hakanen (PhD student), Ville Junnila (Postdoctoral Researcher), Jyrki Lahtonen (University Lecturer), Tuomo Lehtilä (PhD student)
The group studies theoretical aspects of computing and discrete dynamical systems. Focus areas are combinatorics on words, automata theory and symbolic dynamics. The research involves combinatorial and algebraic topics in these areas as well as decidability problems and other algorithmic questions.

The Developments in Language Theory (DLT) Symposium has decided to create a prize to be awarded during the DLT conference. The SALOMAA PRIZE is named to honour the scientific achievements and influence of Academician Arto Salomaa, a founder of the DLT symposium. The prize consists of a diploma and 2.000 euros, funded by the University of Turku, Finland, the home university of Arto Salomaa.
The award is given to a distinguished researcher on his/her fundamental achievements on automata theory and related topics. The achievement might be a single article, a series of articles, or a broader impact on the theory. The criteria is the scientific excellence. Any researcher on automata theory is eligible to the prize.
The first prize was awarded during DLT 2018 in Tokyo, Japan.
There is an open call for nominations of the Salomaa Prize. A detailed nomination letter, following the instructions in the guidelines, should be sent to the chair of the prize committee:
Prof. Juhani Karhumäki
Department of Mathematics and Statistics
University of Turku, Finland
20014 Turun yliopisto, FINLAND
The nominations can be sent either by email or by ordinary mail.
Please find more information about the Salomaa Prize from this page: Salomaa Prize.
The number theoretic research at the University of Turku was initiated by late professor Kustaa Inkeri (1908-1997). Nowadays the research concentrates mostly on analytic number theory, and topics studied by the research group include prime numbers, multiplicative functions and connections to additive combinatorics.

Due to its multidisciplinary nature between statistics and economics, research on time series analysis and econometrics in the University of Turku is carried out jointly at the Department of Mathematics and Statistics (The Center of Statistics) and Turku School of Economics (especially Department of Economics and Department of Accounting and Finance).
The research topics contain new nonlinear econometric methods applied mainly in the analysis of financial and macroeconomic time series. Equally important to the development of new econometric techniques are the empirical applications to macroeconomics and finance, shedding light on the behavior of macroeconomy and financial markets. More specifically, the ongoing research include new estimation and forecasting methods for limited dependent time series, such as binary and non-negative variables, and multivariate methods needed, for example, in structural economic policy analysis and forecasting business cycle fluctuations and financial crises.
