摘要 研究广义旗流形SP(3)/U2(1)×SU(2)上的爱因斯坦度量,应用引理2求其上的非零结构常数,利用计算Grobner基的方法求爱因斯坦方程组的解.得到旗流形SP(3)/U2(1)×SU(2)上在差常数倍的情况下有十二个不变的爱因斯坦度量. The invariant Einstein metrics on the generalized flag manifold SP(3)/U2 (1)×SU(2) is studied in this paper,the non-zero structure constants can be computed applying the method of Lemma 2 and the solutions of the system of the Einstein equation was obtained by computing Grobner basis.Thus,there are twelve Einstein metrics on the flag manifold of SP(3)/U2 (1)XSU(2) (up to a scale).
