Abstract
We find that there exists an elementary topological current in Bose-Einstei
n condensation. Based on the phi-mapping topological current theory, the im
plicit function theorem and the Taylor expansion, the topological structure
of vortex lines is detailed in the neighborhoods of the bifurcation points
of the condensate wave function.
