This year the Corfu2021 activities consist of one school and seven workshops, bringing together world class scientists and young researchers to interact and forge new collaborations. In parallel to the main scientific programme, a rich programme of outreach activities is planned. This includes master classes for high school students, seminars for high school teachers, open talks for the general public, a CERN exhibition and interviews in the media (TV, radio and newspapers).

The Corfu Summer Institute meetings consist of a series of high quality scientific events aiming in the training of young researchers as well as the exchange of knowledge and the collaboration among experienced scientists in the research area of Elementary Particle Physics and Gravity.

It is generally expected that due to the interplay between gravity and quantum mechanics, the classical picture of smooth spacetime manifolds should be replaced by some kind of quantum geometry at very short scales.

Much research has been devoted to this question in the past from various points of view. In particular, the study of quantum field theory on non commutative spacetimes has been developed as an effective approach to study physical models on quantum spaces. The workshop focused mainly

- on various aspects of field theories defined on non commutative spaces and
- on the relation among quantum , non commutative geometries and gravity in different approaches.
