You can also submit your abstract for one of the Special Tracks, but please note:

There are limited places available in the sessions of the Special Tracks. The track conveners have to be critical who they allow to present in their Special Tracks. They will assess the abstracts according to the theme and quality. If your abstract is not approved for the Special Track of your choice, because it does not entirely match with the respective theme but the quality is sufficient, your abstract will automatically be included in the general workshop program. Therefore please also indicate one or more of the main conference themes that match the most with your topic.
