Abstract
It is proven that for Bose-Einstein condensation, in the sense of quasiaverages, condensation into any one-particle state is forbidden at nonzero temperatures in any two-dimensional system, whether under rotation or not, regardless of the external potential, so long as the particle density is bounded everywhere. The proof is based on Bogolyubov's inequality.Keywords
