Star Formation Close to Sgr A* and Beyond the Nuclear Cluster
  Two modes of star formation are involved to explain the origin of young stars
near Sgr A*. One is a disk-based mode, which explains the disk of stars
orbiting Sgr A*. The other is the standard cloud-based mode observed in the
Galactic disk. We discuss each of these modes of star formation and apply these
ideas to the inner few parsecs of Sgr A*. In particular, we focus on the latter
mode in more detail. We also discuss how the tidal force exerted by the nuclear
cluster makes the Roche density approaching zero and contributes to the
collapse of molecular clouds located tens of parsecs away from Sgr A*.
