The conference is over now - if you want to some photos, click the image !

The conference is over now and all of us (hopefully) spent a nice week in Bad Hofgastein. Below you can find a summary of the program with the possibility to see the abstracts online (and to download them). Please forgive us the errors in the abstracts, they are mainly due to conversion problems from tex to html - we hope to eliminate them in the next days. If it was possible, we also put some more informations online. If anyone wants to add her or his talk, just send us what you want to be published (tex, txt or html files are preferred, but we take all you want to send us. If your data is not digital, just fax them to us : +43 1 4277 9518, weŽll try to put them online). If there are any JavaScript Problems, and you can't view the abstracts, then please use the Abstract Overview.
