A Model of Two-Dimensional Quantum Gravity in the Strong Coupling Regime

Abstract

A model of two-dimensional quantum gravity that is the analog of the tensionless string is proposed. The gravitational constant ($k$) is the analog of the Regge slope (${\alpha }^{{}^{\prime }}$) and it shows that when $k\to \infty$, $2D$ quantum gravity can be understood as a tensionless string theory embeded in a two-dimensional target space. The temporal coordinate of the target space play the role of time and the wave function can be interpreted as in standard quantum mechanics.
