For a spacetime of odd dimensions endowed with unit vector field, we introduce new topological current that is identically conserved and whose charge equal to the Euler character even dimensional spacelike foliations. The existence this allows us Chern-Simons-type terms in effective field theories describing relativistic quantum Hall states (2 + 1) superfluids. Using theory, calculate various correlation functions identify transport coefficients. In case, provides natural generalization Wen-Zee term, required characterize shift viscosity systems. superfluid case term have nonzero describe superfluids non s-wave pairing.
