Query: Stability in the energy space for chains of solitons of the
  one-dimensional Gross-Pitaevskii equation   We establish the stability in the energy space for sums of solitons of the
one-dimensional Gross-Pitaevskii equation when their speeds are mutually
distinct and distinct from zero, and when the solitons are initially
well-separated and spatially ordered according to their speeds.
