Noncommutativity in the Kerr-Singer model

We consider the Kerr-Singer model with a noncommutative gauge group as a model of the inflationary era. We study the quantum fluctuations of the model in the metric and the curvature potentials and compute the noncommutativity term in the Kerr-Singer model. We find the noncommutativity term to be noncommutative. We also find that the noncommutativity term is associated with the rotation.
