Centro-affine normal flows on curves: Harnack estimates and ancient solutions
Annales de l'I.H.P. Analyse non linéaire, Tome 32 (2015) no. 6, pp. 1189-1197.

We prove that the only compact, origin-symmetric, strictly convex ancient solutions of the planar p centro-affine normal flows are contracting origin-centered ellipses.
