We prove that for any positive integers n 1 , n 2 ,…, n k , there exists a real flag manifold F (1,…, 1, n 1 , n 2 , …, n k ) with cup-length equal to its dimension. Additionally, we give a necessary condition that an arbitrary real flag manifold needs to satisfy in order to have cup-length equal to its dimension.

在杯长等于其尺寸的真实旗形歧管上

我们证明对于任何正整数 n 1 , n 2 ,…, nk ,存在一个实数标志流形 F (1,…, 1, n 1 , n 2 , …, nk ),其杯长等于其维度。此外,我们给出了一个必要条件,即任意实旗流形需要满足才能使杯长等于其尺寸。
