Description

The general subject of the workshop is quantum gravity in all its aspects and approaches. The fundamental definition of the theory is the focal topic, especially for the first 3 days, together with possible physical applications, especially in the last day. We aim at stimulating exchanges between different approaches to quantum gravity, and the many researchers working on it at various institutions.

The workshop will set the framework for new collaborations between researchers working on such fundamental issues, as well as strengthening the ties among research institutes involved.
