We show that a strict, nearly Kähler 6-manifold with either second or third Betti number nonzero is linearly unstable with respect to the $$\nu $$ ν -entropy of Perelman and hence is dynamically unstable for the Ricci flow.

关于近 Kähler 6-流形的线性稳定性

我们表明,对于 Perelman 的 $$\nu $$ ν -熵,具有第二个或第三个 Betti 数非零的严格的、接近 Kähler 6-流形是线性不稳定的,因此对于 Ricci 流是动态不稳定的。
