Abstract
We obtained the analog for the Luttinger relation for a commensuratespin-density-wave state. We show that while the relation between the area ofthe occupied states and the density of particles gets modified in a simpleand predictable way when the system becomes ordered, a perturbativeconsideration of the Luttinger theorem does not work due to the presence ofan anomaly similar to chiral anomaly in quantum electrodynamics.
