摘要 本文研究了迷向和为五的广义旗流形上的不变爱因斯坦度量的问题.利用计算Grbner基的方法来研究爱因斯坦方程组的解,获得了广义旗流形SO(7)/U(1)×U(2)上的不变爱因斯坦度量的结果,推广了利用数学实验里的用Nsolve command命令来计算爱因斯坦方程组的结果. In this paper, we study the problem of the invariant Einstein metrics on the generalized flag manifold. By computing Gr5bner basis, we obtain the solutions of the system of the Einstein equation, and get the results of invariant Einstein metrics of the generalized flag manifold S0(7)/U(1)× U(2), which promote the original method in the mathematical (Nsolve command) to compute the solutions of the system of the Einstein equation.
