A Continuum Approach to 2D-Quantum Gravity for C>1
M. Martellini, M. Spreafico, K. Yoshida
A Lagrangian continuum model for a string theory with central charge is formulated by incorporating Weyl and diffeomorphism gauge fixing. In particular the tachyon scattering…

2+1 Dimensional Quantum Gravity as a Gaussian Fermionic System and the 3D-Ising Model
Giuseppe Bonacina, Maurizio Martellini, Mario Rasetti
We show that 2+1-dimensional Euclidean quantum gravity is equivalent, under some mild topological assumptions, to a Gaussian fermionic system. In particular, for manifolds topologi…
