The Arf—invariant and the Arnold invariants of plane curves

1997
In [A] V.I.Arnold considered closed generic plane curves, i.e. immersions S 1 → R 2 , the images of which have no singularities except simple (double) self-intersections. In a generic one-parameter family of immersions three types of modifications (“perestroykas”) of generic curves can be met.
