Popis:	The present paper aims at deriving a systematic expression of the second order reduced density matrixΩ 2 in the case of a condensed system of identical spinless bosons. The derivation lends itself to generalization leading to higher order reduced density matricesΩ n ,n>2, that are consistent with the hierarchical set of equations of motion for the differentΩ n .
