证明了商映射Un,d到Un,d/G的有理上同调Leray谱序列在E2退化,其中Un,d是PP^n(C)中d次光滑超曲面方程的仿射簇,G是一般线性群.
We prove that the Leray spectral sequence in rational cohomology for the quotient map $U_{n,d} \to U_{n,d}/G$ where $U_{n,d}$ is the affine variety of equations for smooth hypersurfaces of degree $d$ in $\PP^n(\C)$ and $G$ is the general linear group, degenerates at $E_2$.
