•Quantify correlations between the neutron skin and other quantities
characterizing finite nuclei and infinite nuclear matter.
•How will additional data on neutron-rich nuclei (e.g., masses) help us
constraining the neutron skin?
•Can one make reliable estimates of neutron-to-proton radii for open-shell
nuclei, important in the context of parity violation, where deformation and
pairing effects are large?
•Quantify the regions of instability of the nuclear energy density functional
•Is there an evidence for the isovector component of the pairing functional?
