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. In view of the current COVID-19 crisis we have extended the deadline for submission. The abstracts in English or Greek should be submitted until 29th May 2020 at firstname.lastname@example.org. 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.
