Dear Students,
From now on, the lectures will be given through videos and slides that I will upload once or twice per week, you will find the links in the calendar. The first lecture is already online. Each video will have two versions (english and greek commentary). In the meantime, you are enouraged to use the forum for questions and also try to participate and contribute in the forum discussion. In addition, I will be available on Zoom during the office hours.
G.K.
