For abstracts of talks to be published on-line and in the meeting programme, they have to be submitted by May 1. The organizers appreciate the cooperation of all speakers in observing this important deadline.

If an abstract needs to be changed or adjusted after submission, a new abstract has to be submitted, which will replace the previous version. Before posting abstracts to the website, we verify them manually to ensure that the form has not been misused. Posting of new and revised abstracts usually takes place within 48 hours.

If you encounter inconsistent display of fonts in your browser, please consult the provided PDF version of the abstract, which corresponds to the printed version.

All speakers whose abstracts are accepted for presentation are expected to register and pay the registration fees. Speakers should register at the lowest rate applicable, i.e. Postdocs can register in the "postdocs" category and speakers (including AMS members) as "speakers".
