Abstract: I study the flavor evolution of a dense neutrino gas by considering vacuum contributions, mat-ter effects and neutrino self-interactions. Assuming a system of two flavors in a uniform matter background, the time evolution of the many-body system in discretized momentum space is com-puted. The multi-angle neutrino-neutrino interactions are treated exactly and compared to both the single-angle approximation and mean field calculations.  I study various configurations of up to twenty neutrinos.
