Bifurcations of affine invariants for one-parameter family of generic convex plane curves Takashi Sano — 1999 Banach Center Publications We study affine invariants of plane curves from the view point of the singularity theory of smooth functions. We describe how affine vertices and affine inflexions are created and destroyed.
