Unfortunately, due to the current coronavirus pandemic, the Symposium planned to June 2020 in Porto cannot take place. The executive board of ISDG has decided to postpone it to the next year. Preliminary, the Symposium will be held in June 2021 also in Porto, Portugal, but more exact information will be published later. Since the talks submitted this time can be presented somewhere else, a new process for submitting abstracts will be initiated next Winter.
The web-site of the forthcoming Workshop (which will be help in Saint-Petersburg, Russia, jointly with the 13th International Conference on Game Theory and Management) is open!
