Abstract The momentum-space topology of phase slippage in superfluid 3 He flowing through a narrow channel is discussed, on the basis of numerical integration of the time-dependent Ginzburg-Landau equations. Here the phase-slip processes are associated with superfluid-core phase-slip centers — delocalized in space-time.
