We derive a viscosity from gravitational instability in self-gravitatingaccretion disks, which has the required properties to account for the observedfast formation of the first super-massive black holes in highly redshiftedquasars and for the cosmological evolution of the black hole-mass distribution.Comment: 14 pages, 1 figure, ApJ Letters (in press
