Course overview and goals
In Kähler geometry, the existence problem of canonical Kähler metrics such as Kähler-Einstein metrics or Kähler metrics with constant scalar curvature (cscK metric) is one of the central problems and is still being studied. In this course, we will discuss the existence problem and related topics of the new canonical Kähler metric called the HcscK metric recently introduced by Scarpa and Stoppa. The aim of this course is to provide an understanding of the basics.
Course description and aims
・Understand the definition and basic properties of Kähler manifolds
・Be familiar with curvature
・Understand that the scalar curvature can be regarded as a moment map
・Understand the definition and basic properties of the HcscK system and HcscK metrics
Keywords
Kähler manifolds, cscK metrics, Hyperkähler manifolds, Hyperkähler moment map, HcscK system, HcscK metrics, K-stability
