It has recently been realized that neutrino-neutrino scatterings can have a significant impact on the neutrino flavor evolution in dense neutrino gases, such as supernovae and the early Universe. We generalize the equations used in the description of these systems to allow for nonstandard interactions between neutrinos and consider their impact on the flavor evolution.
