Donaldson–Sun conjecture on asymptotic Bergman kernel bounds

About 5 years old · traced to

Let n∈Nn\in\mathbb{N}, c,d>0c,d>0, and η∈(0,1)\eta\in(0,1). Let (M,ω,L,h)(M,\omega,\mathcal{L},h) be a polarized Kähler manifold with ∣Ric⁡∣≤1|\operatorname{Ric}|\leq 1 and diam⁡(M,ω)≤d\operatorname{diam}(M,\omega)\leq d. Suppose that every metric rr-ball in MM satisfies

Vol⁡(Br)≥cπnn!r2n,∀r∈(0,d).\operatorname{Vol}(B_r)\geq c\frac{\pi^n}{n!}r^{2n},\qquad \forall r\in(0,d).

Let D=D(c)D=D(c) be the least integer such that every integer less than or equal to c−1c^{-1} divides DD. Donaldson–Sun's conjecture. There is a number m0m_0 such that

η≤(mD)−nρmD≤1cη,∀m>m0.\eta\leq (mD)^{-n}\rho_{mD}\leq\frac{1}{c\eta},\qquad \forall m>m_0.

This conjecture asserts that, under two-sided Ricci curvature, diameter, and non-collapsing volume-ratio bounds, the normalized Bergman kernel is uniformly controlled from below and above for all sufficiently large multiples of DD.
