The abstract must be submitted via the Indico tool (see below). It should not exceed 1500 characters (including header and empty lines). In addition, except for the invited talks, it must be accompanied by one full size page (A4, PDF) of more detailed information in order to allow the selection committee to make a sound decision. It should put the emphasis on new developments or at least reflect the progress achieved since the last Conference (2019). Please keep in mind that the presentation time for contributed talks is 20 minutes (plus additional 5 minutes discussion time). For invited talks only the abstract is needed.
