我们考虑了Riemannian度量空间的共形不变泛函,计算了它的第一变分公式,并得到了它的临界点的一些例子。然后,我们计算了关于上述例子的共形不变泛函的第二变分,得到了一些稳定性结果。这些结果推广了小林(J Math Soc Jpn 37:373-389,1985)的定理。
We consider a conformally invariant functional of the space of Riemannian metrics, compute its first variational formula and obtain some examples of its critical point. Then we compute the second variation of the conformally invariant functional about the above examples and get some stability results. These results extend theorems of Kobayashi (J Math Soc Jpn 37:373–389, 1985).
