Semi-flat constant scalar curvature K\"ahler metric on elliptic surface

Differential Geometry 2025-10-17 v2

Abstract

We introduce and construct a novel type of canonical metric: the semi-flat constant scalar curvature K\"ahler (semi-flat cscK) current, which naturally arises in Calabi-Yau fibrations. For a given elliptic surface XX with a holomorphic section, We explicitly construct the desired semi-flat cscK current and analyze its behavior along singular parts. We establish its uniqueness under the condition that XX possesses at least one singular fiber other than of type IbI_b or IbI_b^*. These results contribute to a geometric uniformization program for elliptic surfaces.
