  We propose an effective low-energy theory for ferromagnetic Hall states. It
describes the charge degrees of freedom, on the edge, by a (1 + 1) dimensional
chiral boson theory, and the spin degrees of freedom by the (2 + 1)dimensional
quantum ferromagnet theory in the spin-wave approximation. The usual chiral
boson theory for spinless electrons is modified to include the charge degrees
of freedom with spin. Our total, bulk plus edge, effective action is gauge
invariant and we find a generalized "chiral anomaly" in this case. We describe
two, charged and neutral, sets of edge spin-wave solutions. The spreading of
these waves is much larger than the one for the charge (edge) waves and they
have linear dispersion relations.
