Scientific paper

The amplification of one-armed corrugation waves by viscous processes in the innermost region of relativistic accretion disks is examined. The Kerr metric is adopted. The unperturbed disk is geometrically thin, but its vertical structure is taken into account in examining wave phenomena. The radial wavelength of the waves is assumed to be so short that a local treatment of waves is allowed in the radial direction. If the viscosity is isotropic, the cases when one-armed corrugation waves are amplified is rather restricted: only in a region close to the inner edge of the disk, and only when the central object rotates. If the viscosity is anisotropic in the sense that eddies contributing to the viscosity have longer sizes in the horizontal plane than in the vertical direction, the disk is unstable against the waves in a wider region of the inner disks. This result does not much depend on the parameter dependences of the viscosity.
