Curvature Formula for Direct Images of Relative Canonical Bundles with Poincaré Type Twist
Offered By: IMSA via YouTube
Course Description
Overview
Explore a conference talk on the curvature formula for direct images of relative canonical bundles with a Poincaré type twist. Delve into the speaker's presentation of a curvature formula for the L^2 metric on direct images of relative canonical bundles twisted by holomorphic line bundles with positive singular metrics. Examine how this result applies to families of log canonically polarized pairs and its potential to improve the Berndtsson-Paun positivity result in specific big line bundle scenarios. Consider the implications of generalizing this approach to higher direct images for proving Kobayashi hyperbolicity in moduli spaces of log canonically polarised manifolds. Throughout the talk, encounter key concepts such as L2 canonical forms, L2 metrics, Codaras metrics, and intrinsic objects in the context of algebraic geometry and complex analysis.
