Using the geometric quotient of a real algebraic set by the action of a finite group G, we construct invariants of G-affine real algebraic varieties with respect to equivariant homeomorphisms with algebraic graph, including additive invariants with values in Z. The construction requires to consider the wider category of AS-sets.

配备有限群作用的 $$\mathcal {AS}$$AS 集的商和不变量

使用有限群 G 作用下的实代数集的几何商,我们构造了 G 仿射实代数簇的不变量关于等变同胚的代数图,包括值在 Z 中的加性不变量。 构造需要考虑更广泛的 AS 集类别。
