Title: The discrete Gross-Pitaevskii model and condensation in the
single particle ground state

Abstract: In the context of a tight-binding approximation of the
Gross-Pitaevskii energy functional with a random background potential
we want to discuss in dependence on the interaction coupling constant
a criteria when the Gross-Pitaevskii ground state and the single
particle ground state coincide.
