| Abstract: | We analyse the construction of quantum states for the case of gravity and matter using the solution of the 2-submanifold boundary value problem and “sum over paths” quantisation. This leads to a specification of such states in terms of a complete commuting set of operators. The “sum over topologies” definition is obtained only by a very ad hoc assumption which is made precise. The problem of the arbitrariness of the background metric discussed and resolved by analogy with QED. |
