Arbitrary Spacetimes from the SL(2,R)/U(1) Coset Model
N. Mohammedi
We show that the gauged SL(2,R) WZWN model yields arbitrary spacetimes in two dimensions. The c = 1 matter field and the black hole singularity are just two particular cases in the…

Discrete Symmetry, Non-Commutative Geometry and Gravity
N. Mohammedi
We describe the geomety of a set of scalar fields coupled to gravity. We consider the formalism of a differential Z_2-graded algebra of matrices whose elements are diff…

A Non Degenerate Semi-Classical Lagrangian for Dilaton-Gravity in Two Dimensions
Noureddine Mohammedi
An action for two dimensional gravity conformally coupled to two dilaton-type fields is analysed. Classically, the theory has some exact solutions. These include configurations rep…
