Weil-Petersson度量的渐近性

Asymptotics of the Weil-Petersson metric

Rafe Mazzeo, Jan Swoboda

摘要:

本文研究了亏格为$γ>1$的紧致曲面上共形结构的黎曼模空间$\mathcal M_γ$及其Weil-Petersson度量$g_{\mathrm{WP}}$ .我们的主要结果是:$g_{\mathrm{WP}}$允许一个关于短测地线长度的幂的完全多齐次展开,直到$\mathcal M_γ$的Deligne-Mumford紧化的奇异因子为止.

英文摘要:

We consider the Riemann moduli space $\mathcal M_γ$ of conformal structures on a compact surface of genus $γ>1$ together with its Weil-Petersson metric $g_{\mathrm{WP}}$. Our main result is that $g_{\mathrm{WP}}$ admits a complete polyhomogeneous expansion in powers of the lengths of the short geodesics up to the singular divisors of the Deligne-Mumford compactification of $\mathcal M_γ$.
