    "NLS ground states on metric graphs"

    Abstract
    We investigate the existence of ground states for the subcritical
    NLS energy on metric graphs. In particular, we describe a sufficient
    condition for the existence of ground states and a topological
    assumption that prevents existence. In order to obtain the results,
    we introduce a new rearrangement technique, adapted to the graph
    where it applies. Owing to such a technique, the energy level of the
    rearranged function is improved byconveniently mixing the symmetric
    and monotone rearrangement procedures.
