DESCRIPTION:Adaptive optics observations of nearby AGN\, at spatial resolu
 tions as\nsmall as 0.085"\, show strong evidence for recent - but no longe
 r active -\nstar formation that has occurred in very dense thick nuclear d
 isks. I\ndiscuss the impact of stellar evolution on the inflow of gas to f
 uel the\nAGN by combining a phenomenological approach with analytical mode
 lling and\nhydrodynamic simulations. These complementary perspectives pain
 t a picture\nin which all the processes are ultimately regulated by the ma
 ss accretion\nrate into the central hundred parsecs\, and the ensuing star
 burst that\noccurs there. The resulting supernovae delay accretion by gene
 rating a\nstarburst wind\, which leaves behind a clumpy interstellar mediu
 m. This\nprovides an ideal environment for slower stellar outflows to accr
 ete\ninwards and form a dense turbulent disk on scales of a few parsecs. \
 nSuch a scenario may resolve the discrepancy between the larger scale \nst
 ructure seen with adaptive optics and the small scale structure seen \nwit
 h VLTI.\n
