Indefinite Affine Hyperspheres Admitting a Pointwise Symmetry. Part 2

Symmetry, Integrability and Geometry: Methods and Applications, 2009
An affine hypersurface M is said to admit a pointwise symmetry, if there exists a subgroup G of Aut(T_pM) for all p in M, which preserves (pointwise) the affine metric h, the difference tensor K and the affine shape operator S.

Sums of squares, Hankel index and almost real rank

Forum of Mathematics, Sigma
The Hankel index of a real variety X is an invariant that quantifies the difference between nonnegative quadrics and sums of squares on X. In [5], the authors proved an intriguing bound on the Hankel index in terms of the Green–Lazarsfeld index, which ...
