Geometry and Mathematical Physics Group

Quantum Gravity and Quantum Fields Theory : Physical, Mathematical and Philosophical perspectives

Scientific Program

Each talk will take 40 minutes: 25 minutes presentations followed by a 10 minutes discussions. There will be also a short lectures of 20 minutes : 15 minutes presentations and 5 minutes discussions. The discussions times are not indicated in the schedule, but our idea is that they will indeed be utilized fully!
