Abstract
We construct exact solutions to Einstein equations representing relati vistic disks embedded in an expanding FRW universe. We show that the e xpansion influences kinematical characteristics of the disks, such as rotational curves, surface mass density, etc. The effects of the expan sion are exemplified with nonstatic generalizations of Kuzmin-Curzon a nd Schwarzschild disks.
