Query: On asymptotic stability of ground states of some systems of nonlinear
  Schr\"odinger equations   We extend to a specific class of systems of nonlinear Schr\"odinger equations
(NLS) the theory of asymptotic stability of ground states already proved for
the scalar NLS. Here the key point is the choice of an adequate system of
modulation coordinates and the novelty, compared to the scalar NLS, is the fact
that the group of symmetries of the system is non-commutative.
