Abstract
We generalize a recent study of the stability of isotropic (spherical) rota ting membranes to the anisotropic ellipsoidal membrane. We find that while the stability persists for deformations of spin l=1, the quadrupole and hig her spin deformations (l greater than or equal to2) lead to instabilities. We find the relevant instability modes and the corresponding eigenvalues. T hese indicate that the ellipsoidal rotating membranes generically decay int o fingerlike configurations.
