Trapping of Non-Axisymmetric $g$-Mode Oscillations in Thin Relativistic Disks and kHz QPOs

We suggest that in the inner part of geometrically thin relativistic disks there are trapped non-axisymmetric $g$-mode oscillations which are excited by a corotation resonance. These oscillation modes would be the cause of quasi-periodic kHz oscillations observed in some low-mass X-ray sources.
