在经典镜像对称理论的启发下,我们研究了Calabi-Yau三重体的复杂Kähler锥上的某些Kähler度量,推测对应于该镜像在大复杂结构极限附近的Weil-Petersson度量的近似。特别地,在Kähler锥的水平集上自然定义的黎曼度规(通过杯积定义)被看作是类似于在大复杂结构极限附近的韦尔-彼得森度规的一个片段。这使我们能够给出Ooguri和Vafa猜想的反例,即Weil-Petersson度规在大型复杂结构极限点的某些邻域具有非正标量曲率。
Motivated by the classical statements of Mirror Symmetry, we study certain Kähler metrics on the complexified Kähler cone of a Calabi–Yau threefold, conjecturally corresponding to approximations to the Weil–Petersson metric near large complex structure limit for the mirror. In particular, the naturally defined Riemannian metric (defined via cup-product) on a level set of the Kähler cone is seen to be analogous to a slice of the Weil–Petersson metric near large complex structure limit. This enables us to give counterexamples to a conjecture of Ooguri and Vafa that the Weil–Petersson metric has non-positive scalar curvature in some neighborhood of the large complex structure limit point.
