Abstract: Some aspects of disk–halo interactions for models of disk galaxies in and out of equilibrium are reviewed. Specifically, we focus on disk–halo resonant interaction without and in the presence of a gas component. Another issue is disk growth within an assembling triaxial dark matter halo. We argue that while the triaxiality is the result of the merger process and the radial orbit instability, it is the developing chaos that damps the first generation of bars and washes out the halo prolateness. This chaos is triggered by the gravitational quadrupole interaction(s) in the system and supported by a number of other processes characteristic of baryons.
