Perelman $\mathcal{W}$ -泛函的全二阶变分

The total second variation of Perelman's $\mathcal{W}$-functional

Nefton Pali

摘要:

给出了Perelman $\mathcal{W}$ -泛函在黎曼度量空间任意点处的一个非常简单而一般的全二阶变分公式.此外,我们进行了研究的性质的变化的Kähler结构。我们推导出Perelman $\mathcal{W}$ -泛函关于这种变分的一个相当简单而一般的全二阶变分公式。在这种情况下,公式中的主热强烈地依赖于复结构的变化。我们还发现凸的Perelman的$\mathcal{W}$ -功能沿特定的变化点与非负Bakry-Emery-Ricci张量。

英文摘要:

We show a very simple and general total second variation formula for Perelman's $\mathcal{W}$-functional at arbitrary points in the space of Riemannian metrics. Moreover we perform a study of the properties of the variations of Kähler structures. We deduce a quite simple and general total second variation formula for Perelman's $\mathcal{W}$-functional with respect to such variations. In this case the main therm in the formula depends strongly on the variation of the complex structure. We discover also convexity of Perelman's $\mathcal{W}$-functional along particular variations over points with non-negative Bakry-Emery-Ricci tensor.
