摘要翻译:
我们将所有Picard数为1的光滑射影星形变体分类。我们证明了任意这类X的自同构群至多作用于两个轨道,并且这个群仍然只作用于在封闭轨道上爆炸的X上的两个轨道。我们刻划了所有满足后一性质的Picard数为1的光滑射影双轨道簇。

英文摘要:
We classify all smooth projective horospherical varieties with Picard number 1. We prove that the automorphism group of any such variety X acts with at most two orbits and that this group still acts with only two orbits on X blown up at the closed orbit. We characterize all smooth projective two-orbits varieties with Picard number 1 that satisfy this latter property.
