Abstract
The existence of topological defects, known as skyrmions, within the s pin excitons energy band of a 2D electron gas under a strong magnetic field at filling factor nu = 1 is investigated within the Hartree-Fock approximation. Using the linear momentum representation, it is shown that the inhomogeneity created in the system by a charged skyrmion can be described by a nonuniform rotation of the spin density operators i n a condensate of spin excitons.
