摘要：

In this article we introduce a differential equation for the first order correlation function G((1)) of a Bose-Einstein condensate at T = 0. The Bogoliubov approximation is used. Our approach points out directly the dependence on the physical parameters. Furthermore it suggests a numerical method to calculate G((1)) without solving an eigenvector problem. The G((1)) equation is generalized to the case of non zero temperature.
