We examine a recent deformation of three-dimensional anti-deSitter gravity based on non-commutative Chern-Simons theory with gauge group U (1, 1) × U (1, 1). In addition to a non-commutative analogue of 3D gravity, the theory contains two addition gauge fields which decouple in the commutative limit. It is well known that the level is quantized in noncom-mutative Chern-Simons theory. Here it implies that the cosmological constant goes like minus one over an integer-squared. We construct the… CONTINUE READING
