Two-Dimensional Quantum Gravity in Temporal Gauge
M. Fukuma, N. Ishibashi, H. Kawai, M. Ninomiya
Abstract
We propose a new type of gauge in two-dimensional quantum gravity. We investigate pure gravity in this gauge, and find that the system reduces to quantum mechanics of loop length l. Furthermore, we rederive the c\!=\!0 string field theory which was discovered recently. In particular, the pregeometric form of the Hamiltonian is naturally reproduced.
