»The J2+-invariant for pairs of generic immersions«

Abstract:
We will introduce the J2+-invariant for pairs of generic immersions. The new invariant behaves like Arnold's J+-invariant for generic immersions as it is invariant under homotopy including inverse tangencies and traversing triple points, but changes by traversing direct tangencies. It has several other properties, for example the invariant for pairs is completely independent of the J+-invariants of the single immersions, which we will prove in Theorem B.
