First Announcement of the meeting Analytic and Geometric Methods in Inverse Problems, Helsinki, Finland, August 25-29 2003 The Finnish Inverse Problems Society together with the Finnish Mathematical Society arranges a theme year of inverse problems in Finland during the academic year 2003-2004. The theme year includes a series of conferences and intensive courses on inverse problems and related topics in mathematics. The aim of the meeting entitled Analytic and Geometric Methods in Inverse Problems is to bring together a number of specialists in inverse problems, and in particular to focus on modern analytic and geometric tools. The preliminary list of invited speakers includes: Carlos Alves Juan Antonio Barcelo Elena Beretta Khosrow Chadan David Colton Allan Greenleaf Alberto Grunbaum Martijn de Hoop David Isaacson Alexander Katchalov Rainer Kress Yaroslav V. Kurylev Stephen McDowall Adrian Nachman Clifford Nolan Alberto Ruiz William Rundell Vladimir Sharafutdinov Gunther Uhlmann Michael Vogelius We ask the interested to visit the web page of the theme year, http://www.math.hut.fi/inverseyear/ where you find the necessary information about registration and accommodation. Please note that the deadline for the early registration is April 30, 2003. Just after the opening conference on September 1.-5., there will be a Workshop on Inverse Spectral Problems. It is sponsored by the European Science Foundation's programme Partial Differential Operators and Spectral Theory. The main speakers here are Maciej Zworski (University of Berkeley) Carolyn Gordon (Dartmouth College) David L. Webb (Dartmouth College) Peter Perry (University of Kentucky) Michiel van den Berg (University of Bristol) Slava Kurylev (University of Loughborough) Matti Lassas (University of Helsinki) If you are going to participate in the workshop you should mention this when you do the registration. For young researchers and graduate students, financial support towards the expenses of participation is available both for the opening conference of the theme year and the workshop.
