Quantum Gravity Colloquium 5

6 Oct 2010, 10:00 → 8 Oct 2010, 19:00 Europe/Zurich

454A - Klee, 4th floor (Thursday morning: 646A - Mondrian, 6th floor) (Laboratoire APC, University Paris 7)

A colloquium to facilitate discussion and exchange between the PhD students in the area of Quantum Gravity.

The primary purpose of this colloquia is to provide a framework for PhD students in Quantum Gravity and related areas to present their own work, and facilitate discussion outside the scope of ones own project.
