微分几何 2021-05-12 v5

摘要

π:XM\pi:\mathcal{X}\to M 为具有紧纤维的全纯纤维化,LLX\mathcal{X} 上的相对丰沛线丛。对于大的 kk,我们得到了直像丛 π(LkKX/M)\pi_*(L^k\otimes K_{\mathcal{X}/M})L2L^2-度规和 Quillen 度规的曲率渐近展开,直至低于 kn1k^{n-1} 的低阶项。作为一个应用,我们证明解析挠率 τk(ˉ)\tau_k(\bar{\partial}) 满足 ˉlog(τk(ˉ))2=o(kn1)\partial\bar{\partial}\log(\tau_k(\bar{\partial}))^2=o(k^{n-1}),其中 nn 为纤维的维数。
