On the Weil-Petersson curvature of the moduli space of Riemann surfaces of large genus

Yunhui Wu

Let $S_{g}$ be a closed surface of genus $g$ and $M_{g}$ be the moduli space of $S_{g}$ endowed with the Weil-Petersson metric. In this paper we investigate the Weil-Petersson c…

On positive scalar curvature and moduli of curves

Kefeng Liu, Yunhui Wu

In this article we first show that any finite cover of the moduli space of closed Riemann surfaces of genus $g$ with $g \geq 2$ does not admit any Riemannian metric $d s^{2}$ of nonneg…

Scalar curvatures of Hermitian metrics on the moduli space of Riemann surfaces

Yunhui Wu

In this article we show that any finite cover of the moduli space of closed Riemann surfaces of $g$ genus with $g \geq 2$ does not admit any complete finite-volume Hermitian metric…

The Riemannian Sectional Curvature Operator Of The Weil-Petersson Metric and Its Application

Yunhui Wu

Fix a number $g > 1$ , let $S$ be a close surface of genus $g$ , and $T e i c h (S)$ be the Teichmüller space of $S$ endowed with the Weil-Petersson metric. In this paper we show that the R…

Uniform Bounds for Weil-Petersson Curvatures

Michael Wolf, Yunhui Wu

We find bounds for Weil-Petersson holomorphic sectional curvature, and the Weil-Petersson curvature operator in several regimes, that do not depend on the topology of the underlyin…
