We evaluate general-relativistic effects in motion of stationary accretiondisks around a Schwarzschild black hole, assuming the first post-Newtonian(1PN) approximation. There arises an integrability condition, that leads to theemergence of two types of general-relativistic corrections to a Newtonianrotation curve. The well known geometric dragging of frames acceleratesrotation but the hitherto unknown dynamic term, that reflects the diskstructure, deccelerates rotation. The net result can diminish the Newtonianangular velocity of rotation in a central disk zone but the geometric draggingof frames dominates in the disk boundary zone. Both effects are nonlinear innature and they disappear in the limit of test fluids. Dust disks can be onlygeometrically dragged while uniformly rotating gaseous disk are untouched atthe 1PN order. General-relativistic contributions can strongly affect rotationperiods in Keplerian motion for compact systems.
