<h2><small>"NLS ground states on metric graphs"<br>
<br>
Abstract<br>
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.
