A SPECIAL FORM OF THE PATH INTEGRAL FOR THE MASTER CONSTRAINT OF LOOP QUANTUM GRAVITY
Spin-foams are topological structures that arise frequently in physical theories like loop quantum gravity. These structures are used to compute transition amplitudes. This paper shows a form of the path integral that can be used to calculate spin-foam amplitudes. This path integral is based upon the master constraint of loop quantum gravity. Several mathematical aspects of the path integral are treated in this paper.
spin-foams, path integrals, loop quantum gravity, point-free topology.
