Quantized Volume Comparison for Fano Manifolds, II

Kaixuan Lyu, Kewei Zhang

In this note, the second author's quantized volume comparison conjecture is solved: If is a -semistable Fano manifold of dimension , then for every integer , \[ h…

The sharp volume gap for Kähler manifolds with positive Ricci curvature

Chi Li, Minghao Miao, Kewei Zhang

We prove a sharp volume gap estimate: if an -dimensional compact Kähler manifold satisfies and , then $\mathrm{vol}…

Transcendental Okounkov bodies

Tamás Darvas, Rémi Reboulet, David Witt Nyström +2

We show that the volume of transcendental big -classes on compact Kähler manifolds can be realized by convex bodies, thus answering questions of Lazarsfeld-Mustaţă and De…

Multi-Component Open/Relative/Local Correspondence

Song Yu, Ke Zhang, Zhengyu Zong

For a toric Calabi-Yau 3-orbifold relative to s Aganagic-Vafa outer branes, we prove a correspondence among the genus-zero open Gromov-Witten invariants with maximal winding at eac…

A YTD correspondence for constant scalar curvature metrics

Tamás Darvas, Kewei Zhang

Given a compact Kähler manifold, to better understand Mabuchi's energy we introduce a family of energies, whose favorable properties are similar to those of the Ding en…

Quantized volume comparison for Fano manifolds

Kewei Zhang

A result of Kento Fujita says that the volume of a Kähler-Einstein Fano manifold is bounded from above by the volume of the projective space. In this short note we establish quant…
