| Abstract: | A general low-temperature effective action for the order parameter in the superfluid phase A of helium 3 is derived. In a symmetric case, when the Fermi velocity equals the transverse velocity of low energy fermionic quasiparticles, the action is the standard relativistic electromagnetic action. |
