      abstract     = {Slow flavor evolution (defined as driven by neutrino masses
                      and not necessarily ``slow'') is receiving fresh attention
                      in the context of compact astrophysical environments. In
                      Part~I of this series, we have studied the slow-mode
                      dispersion relation following our recently developed analogy
                      to plasma waves. The concept of resonance between flavor
                      waves in the linear regime and propagating neutrinos is the
                      defining feature of this approach. It is best motivated for
                      weak instabilities, which probably is the most relevant
                      regime in self-consistent astrophysical environments because
                      these will try to eliminate the cause of instability. We
                      here go beyond the dispersion relation alone (which by
                      definition applies to infinite media) and consider the group
                      velocities of unstable modes that determines whether the
                      instability relaxes within the region where it first appears
                      (absolute), or away from it (convective). We show that all
                      weak instabilities are convective so that their further
                      evolution is not local. Therefore, studying their
                      consequences numerically in small boxes from given initial
                      conditions may not always be appropriate.},
