Query: Dynamical friction on Globular Clusters in core-triaxial galaxies: is it
  a cause of massive black hole accretion?   The present work extends and deepens previous examinations of the evolution
of globular cluster orbits in elliptical galaxies, by means of numerical
integrations of a wide set of orbits in 5 self-consistent triaxial galactic
models characterized by a central core and different axial ratios. These models
constitute a valid and complete representation of regular orbits in elliptical
galaxies. Dynamical friction is definitely shown to be an efficient cause of
evolution for the globular cluster systems in elliptical galaxies of any mass
and axial ratios. Moreover, our statistically significant sample of computed
orbits confirm that the globular cluster orbital decay times are, in a wide
range of realistic initial conditions, much shorter than the age of the
galaxies. Consequently, the huge quantity of mass carried into the innermost
galactic region in form of decayed globular clusters have likely contributed
significantly in feeding and accreting a compact object therein.
