Abstract
We have investigated the effect of weak disorder on the ground state of a t wo-dimensioned electron gas in the quantum Hall regime at filling factors s lightly deviating from unity. The Skyrmions and anti-Skyrmions are found to be present even at filling factor v = 1. They may be strongly squeezed by the disorder. We have studied the effect of temperature on Skyrmion density and size.
