Phys. Rev. Lett. 76, 4777–4780 (1996)Higher-Dimensional Bosonization with Nonlinear Energy DispersionReceived 20 February 1996; published in the issue dated 17 June 1996 We develop a systematic method to treat the effect of nonlinearity in the energy dispersion on the usual bosonization result for the single-particle Green's function of fermions in arbitrary dimension. The leading corrections due to the quadratic term in the energy dispersion are explicitly calculated. In the Chern-Simons theory for half-filled quantum Hall systems, curvature is shown to be essential. © 1996 The American Physical Society URL:
