Existence of BoseEinstein condensation in one and two dimensions
Abstract
It is shown that in Bose condensed systems the fsum rule has an additional term due to the condensate reservoir. As a result of this new sum rule and an exact Bogoliubov inequality, BoseEinstein condensation in repulsively interacting systems may occur in one and two dimensions.
