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 is reduced 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.
