Abstract

We construct invariants of birational maps with values in the Kontsevich–Tschinkel group and in the truncated Grothendieck groups of varieties. These invariants are morphisms of groupoids and are well-suited to investigating the structure of the Grothendieck ring and L-equivalence. Building on known constructions of L-equivalence, we prove new unexpected results about Cremona groups.

双向映射的动机不变式 | 数学年鉴

我们构建了在 Kontsevich-Tschinkel 群和截断格罗thendieck 群中具有值的双向映射不变式。这些不变式是群的变形，非常适合研究格罗内狄克环的结构和 L-等价性。在已知的 L 等价性构造的基础上，我们证明了关于克雷莫纳群的意想不到的新结果。
