By analyzing the Ricci star tensor Ric*, we study the harmonic almost complex structure in maximal flag manifolds. We show that flag manifolds have diagonal Ric* tensor. Using the concept of ⁎Einstein manifolds, we study the stability of the invariant almost complex structure and show examples of stables parabolic almost complex structures on maximal flag manifolds.

关于旗流形上几乎不变的不变结构的稳定性

通过分析里奇星张量 C*,我们研究了最大标志流形中的谐波几乎复杂的结构。我们证明旗流形具有对角线C*张量。利用⁎爱因斯坦流形的概念,我们研究了不变的几乎复杂结构的稳定性,并给出了在最大标志流形上稳定的抛物线型几乎复杂结构的例子。
