Leader: Kari Astala (click here for the address of the Helsinki Mathematics deparment)

In Finland, the Helsinki Mathematics department is the leading center of mathematical research. Currently the department participates in several Centers of Excellence nominated by the Academy of Finland, with two of them coordinated from Helsinki. The department occupies a new modern building, offering all modern technological facilities.

Finland has particularly strong traditions in geometric analysis based on conformal and quasiconformal methods, and the Finnish team collects the leading experts in the country, from the universities of Helsinki (HU) and Jyväskylä (JU). In addition the team is joined by groups from geometric measure theory and mathematical physics, where in both the senior members are international leading experts in their fields. The teams have regularly organized conferences and different training activities, with the annual international Jyväskylä summer school offering a regular basis for further training in the topics of this proposal.

Principal researchers for this project:
Kari Astala (HU, Academy Professor; Team Coordinator): Salem Prize 1994, Expert in quasiconformal mappings and their applications. Used dynamical methods to prove the fundamental Gehring-Reich conjecture on qc-mappings. Organized several conferences and summerschools, President of the Finnish mathematical Society. (50%)
