Relaxation of elementary excitations with small wave vectors (magnons) in the nematic phase of magnet with spin S = 1 near antiferromagnetic SU(3) critical point has been studied. In the vicinity of the critical point the dispersion law minimum appears near the border of Brillouin zone. The elementa...
