The Galactic Center compared with nuclei of nearby galaxies
  Understanding our Galactic Center is easier with insights from nearby
galactic nuclei. Both the star formation activity in nuclear gas disks, driven
by bars and nuclear bars, and the fueling of low-luminosity AGN, followed by
feedback of jets, driving molecular outflows, were certainly present in our
Galactic Center, which now appears to be quenched. Comparisons and diagnostics
are reviewed, in particular of m=2 and m=1 modes, lopsidedness, different disk
orientations, and fossil evidences of activity and feedback.
