Abstract
Taking resort to Haldane's spherical geometry we can visualize fractional quantum Hall effect on the noncommutative manifold with and odd. The discrete space leads to the deformation of symplectic structure of the continuous manifold such that the symplectic area is given by with an odd integer which is related to the Berry phase and the filling factor is given by . We here argue that this is equivalent to the noncommutative field theory as prescribed by Susskind and Polychronakos which is characterized by area preserving diffeomorphism. The filling factor is determined from the change in chiral anomaly and hence the Berry phase as envisaged by the star product.
