Author(s): M. A. Zubkov

The definition of topological invariants N˜4, N˜5 suggested in M. A. Zubkov and G. E. Volovik Nucl. Phys. B860 295 (2012) is extended to the case when there are zeros and poles of the Green function in momentum space. It is shown how to extend the index theorem suggested by Zubkov and Volovik to t…
