证明了对于线性代数群作用下线性空间的商空间的光滑紧化，Artin-Mumford双不变量是根据的二维群上同调有效计算的；研究了不变量为非平凡的群的例子。参考书目：6篇。
It is proved that for a smooth compactification of a quotient space of a linear space by the action of a linear algebraic group , the Artin-Mumford birational invariant is effectively computable in terms of the 2-dimensional group cohomology of ; examples of groups for which the invariant is nontrivial are also studied. Bibliography: 6 titles.
