Topics for this special issue will include:

• discrete formulations of gravity, covariant approaches, spin-foam models, causal dynamical triangulations, emergent gravity models;
• Hamiltonian constraint, constraint algebras, Dirac observables, covariance and anomalies, physical states, matter coupling;
• group-theoretical aspects, number-theoretic aspects, non-commutativity;
• phenomenology, non-locality from quantum gravity, black hole entropy, horizon properties, cosmology.

Papers on these or related topics are welcome for this issue.
