Abstract

Taking resort to Haldane's spherical geometry we can visualize fractional quantum Hall effect on the noncommutative manifold M4×ZNM_4 \times Z_N with N>2N>2 and odd. The discrete space leads to the deformation of symplectic structure of the continuous manifold such that the symplectic area is given by p.q=2πm\triangle p.\triangle q=2\pi m \hbar with mm an odd integer which is related to the Berry phase and the filling factor is given by 1m\frac{1}{m}. 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 1m\frac{1}{m} is determined from the change in chiral anomaly and hence the Berry phase as envisaged by the star product.
