Query: Open giant magnons on LLM geometries   We compute sigma model solutions for rigidly rotating open strings suspended
between giant gravitons in general LLM geometries. These solutions are confined
to the LLM plane. These all have a dispersion relation for $\Delta-J$ that is
consistent with saturation of a BPS bound of the centrally extended spin chain.
For the special case of circularly symmetric LLM geometries, we can further
evaluate the amount of angular momentum $J$ carried by these strings. This
quantity diverges for string configurations that try to move between different
"coloring regions" in the LLM plane. All of these quantities have a
perturbative expansion in the t'Hooft coupling. For the strings suspended
between AdS giants, we can compute in field theory the leading result of $J$
carried by the string via an analytic continuation of the $SU(2)$ result, with
the help of the Bethe Ansatz for the $SL(2)$ sector. We thus provide additional
information on how the radial direction of $AdS$ arises from (open) spin chain
calculations.
