论文摘要
我们介绍了模棱两可的伯恩赛德群体，在模棱两可的birational几何形状中的新不变式，概括了有限阿伯利亚群体的行为，这是由于Kontsevich，Pestun和第二作者的范围，并研究了他们的特性。我们为平滑的代数品种的均等型生育类型建立了专业图，并具有有限群的作用。
We introduce equivariant Burnside groups, new invariants in equivariant birational geometry, generalizing birational symbols groups for actions of finite abelian groups, due to Kontsevich, Pestun, and the second author, and study their properties. We establish a specialization map for the equivariant birational type of a smooth algebraic variety with an action of a finite group.
