From the Optimal $L^2$-Estimates \((p,n)\) and \((n,p)\)-Forms to Uniform Griffiths \(p\)-Positivity via Convolution and Restriction

Abstract

We prove that the optimal \(L^2\)-estimate property for \((p,n)\)-forms is preserved under standard convolution regularization. As an application, we show that a singular Hermitian metric satisfying the optimal \(L^2\)-estimate property for \((p,n)\)-forms is uniform Griffiths \(p\)-positive. By establishing the restriction property, we prove that a singular Hermitian metric satisfying the optimal \(L^2\)-estimate property for \((n,p)\)-forms is also uniform Griffiths \(p\)-positive.

On some connections between Kobayashi geometry and pluripotential theory

In this paper, we explore some connections between Kobayashi geometry and the Dirichlet problem for the complex Monge--Ampère equation. Among the results we obtain through these connections are: $(i)$~a theorem on the continuous extension up to $\partial{D}$ of a proper holomorphic map $F: D\longrightarrow Ω$ between domains with $\dim_{\mathbb{C}}(D) < \dim_{\mathbb{C}}(Ω)$, and $(ii)$~a result that establishes the existence of bounded domains with ``nice'' boundary geometry on which Hölder regularity of the solutions to the complex Monge--Ampère equation fails. The first, a result in Kobayashi geometry, relies upon an auxiliary construction that involves solving the complex Monge--Ampère equation with Hölder estimates. The second result relies crucially on a bound for the Kobayashi metric.

Fractional Besov-Sobolev Spaces on Chord-arc Curves

Let $Γ$ be a bounded rectifiable Jordan curve, with complementary domains $Ω_i$ and $Ω_e$. For $1 4$, this principle fails on a suitable radial-Lipschitz domain, showing that the upper bound $4$ cannot be increased uniformly over this class.

Separation properties of a hybrid point process with determinantal radii and uniform arguments

We recently characterized the almost sure separation of determinantal point processes $Λ_ϕ$ in the plane associated with Fock spaces $\mathcal F_ϕ$ with doubling weights $ϕ$. We also showed that, as expected, a more restrictive condition is required to characterize the almost surely separated Poisson processes with the same first intensity as $Λ_ϕ$. To gain further insight into this difference in behavior, we focus on radial weights $ϕ$ and introduce a hybrid process $Λ_ϕ^M=\{r_j e^{iθ_j}\}_{j}$, where the moduli $r_j$ are taken from $Λ_ϕ$, while the arguments $θ_j$ are chosen independently and uniformly in $[0,2π)$, independently of the radii. Our main result is that the hybrid process is almost surely separated under exactly the same condition as the corresponding Poisson process. Thus, despite preserving the joint radial distribution of the determinantal process, independent angular randomization destroys its improved separation properties.
