Open problems in Loop Quantum Gravity

Sunday, February 28 - Thursday, March 4, 2010
Zakopane, Poland
(Arrival and departure dates are respectively Feb. 27 and March 5)

The workshop is organised within the framework of the ESF research network Quantum Geometry and Quantum Gravity, coordinated by John Barrett and Hermann Nicolai - see for further information about the network.

Presentation files (most of) are available to download


  • The dynamics of quantum space (the status of the quantum Hamiltonian constraint in LQG and the covariant implementation of the dynamics in spin foam models and group field theories).
  • The semiclassical limit and the continuum approximation in loop quantum gravity and the recovering of classical General Relativity and of matter quantum field theory in such approximation.
  • Quantum gravitational observables.
  • The role of diffeomorphisms in quantum gravity, their nature and possible breaking at the Planck scale or in discrete contexts.
