Secular Evolution of Galaxies: From Dark Halos to Nuclei

{{One path by which disk galaxies evolve is via internal secular
evolution. By breaking the symmetry of the system, bars play an
important role in driving such evolution. I describe some recent
results concerning aspects of this evolution relating to dark halos, disk
density profiles, bulges and central nuclei.}}
