Semi-classical Dynamical Triangulations

Understand

For non-critical string theory the partition function reduces to an integral over moduli space after integrating over matter fields.

• The moduli integrand is known analytically for genus one surfaces.
• The formalism of dynamical triangulations provides us with a regularization of non-critical string theory and we show that even for very small triangulations it reproduces very well the continuum integrand when the central charge $c$ of the matter fields is large negative, thus providing a striking example of how the quantum fluctuations of geometry disappear when $c \to -\infty$.
