We had a hard time deciding on the speakers to invite to our conference, since we have received far more abstracts for talks than we could possible hope to hear on our workshop. If you have submitted an abstract, you should already have received an email in which we inform you whether you have been accepted. If you did not hear from us by now, please get in touch with us. We are very grateful to everybody who submitted an abstract and would be happy to welcome you in Vienna regardless of whether we could accept your paper.
