Query: The magnetospheric accretion/ejection process in young stellar objects:
  open issues and perspectives   This summary talk aims at highlighting some of the remaining open issues
regarding the physics of the magnetospheric accretion/ejection process in young
stellar objects (YSOs). It lists a number of questions related to YSOs magnetic
fields and accretion regimes, the structure and properties of accretion shocks,
the origin of multiple outflow components, and the impact of the star-disk
magnetic interaction onto early angular momentum evolution.
