Abstract
The most general vortex solution of the Liouville equation (which arises in nonrelativistic Chern–Simons theory) is associated with rational functions, f(z)=P(z) ∖Q∥z), where P(z) and Q(z) are both polynomials, deg P<deg Q≡ N. This allows us to prove that the solution depends on 4N parameters without the use of an index theorem, as well as the flux quantization Φ=-Nπ(sign k).
