The Organizing Committee invites all colleagues for the submission of abstracts for papers to be presented either as talks or posters at the CAA-GR 2020. The abstracts and contributions already submitted last year will remain to be considered for presentation. There is no need for re-submission. The authors are free to update or edit their abstracts until the new deadline or to withdraw them. The abstracts in English or Greek should be submitted until 28th May 2021 at email@example.com. A selection of suggested topics can be found here but it is not mandatory. The abstracts will be reviewed by the Scientific Committee, who will decide about acceptance.
