Indefinite Affine Hyperspheres Admitting a Pointwise Symmetry. Part 2

open access: yesSymmetry, 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.

Quadrics on Gushel-Mukai varieties

open access: yes
We study Hilbert schemes of quadrics of dimension $k \in \{0,1,2,3\}$ on smooth Gushel-Mukai varieties $X$ of dimension $n \in \{2,3,4,5,6\}$ by relating them to the relative Hilbert schemes of linear subspaces of dimension $k + 1$ of a certain family ...
