Description
The parquet summation for the two-body vertex is used as the framework for a theory of interacting inhomogeneous boson systems. We present a precisely defined set of aproximations for the single-particle self-energy and for the two-body vertex which lead to a set of equations which are equivalent to the inhomogeneous variational hypernetted-chain theory for inhomogeneous boson system. The present calculation makes clear the distinction between the self-energy which is used in constructing the two-body vertex and the self-energy which one would construct with the two-body vertex.
