On isotrivial cone structures of highest weight type

Yingqi Liu

We study the projective-geometric criterion of Hwang-Li for isotrivial cone structures admitting characteristic conic connections. We give a complete classification of flag varieti…

On linear sections of the spinor tenfold II

Yingqi Liu, Laurent Manivel

Following previous work by A. Kuznetsov, we study the Fano manifolds obtained as linear sections of the spinor tenfold in $P^{15}$ . Up to codimension three there are finit…

Moduli of codimension two linear sections of subadjoint varieties

Yingqi Liu

Let $G$ be a simple algebraic group of type $F_{4}$ , $E_{6}$ , $E_{7}$ or $E_{8}$ , and let $g$ be its Lie algebra. The adjoint variety $X_{ad} \subseteq \mathbb{P} \mathf…

Additive actions on hyperquadrics of corank two

Yingqi Liu

For a projective variety $X$ in $P^{m}$ of dimension $n$ , an additive action on $X$ is an effective action of $G_{a}^{n}$ on $P^{m}$ such that $X$ is $\m…
