2D Gravity with Torsion, Oriented Matroids and 2+2 Dimensions

Abstract

We find a link between oriented matroid theory and 2d gravity with torsion. Our considerations may be useful in the context of noncommutative phase space in a target spacetime of signature (2+2) and in a possible theory of gravity ramification.
