| 英文摘要 | 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 G(a)(n)-invariant and the induced action on X has an open orbit. Arzhantsev and Popovskiy have classified additive actions on hyperquadrics of corank 0 or 1. In this paper, we give the classification of additive actions on hyperquadrics of corank 2 whose singularities are not fixed by the G(a)(n)-action. |
