An analysis is presented of the equilibrium of self-gravitating gaseous disks of finite thickness, with allowance for all corrections of the order h/R, where h and R are the characteristic values of half-thickness and radius. It is shown that it is necessary to take into account corrections of gravitational force to the same order as pressure terms in the radial equilibrium. For a specified polytropic equation of state, a closed system of equations is obtained determining the distribution of surface density in the main part of the disk for a given rotation law. It is also shown that there is a limit of uniform rotation for any polytropic figure of equilibrium, except for an incompressible fluid. An asymptotic relationship is obtained for the maximum oblateness of a figure in the case of limiting rotation.
