Nonlinear interactions among oscillation modes of accretion tori
A formalism of nonlinear coupling of oscillation modes of fluid bodies will be briefly explained and further applied to the oscillations of pseudo-Newtonian slender tori. In particular, the attention is paid to a nonlinear coupling among the epicyclic modes and to a role of unstable modes in exciting the oscillations.
