Helsinki Stochastic Sauna Seminar , December 18-19 2014. 

This is a traditional informal occasion for  PhD students and researchers,  to meet and discuss about  state-of-the-art stochastics, mathematical physics, and statistics. After the scientific part,  on thursday 18.12 everyone is welcome to join for a  traditional finnish sauna in Kotiharjun sauna. The event is organized jointly by Department of Mathematics and Statistics of the University of Helsinki, the Department of Mathematics and System Analysis of Aalto University and the Finnish Graduate Doctoral Program in Stochastics and Statistics FDPSS.  All partecipants are invited to submit a talk, and in case there will be enough talks,  we  continue the program on friday 19.12  after the traditional winter swimming.
