Strichartz estimates for orthonormal systems on compact manifolds: the non-sharp region

Hongzhou Ji, Liping Xu, An Zhang

We establish new Strichartz estimates for orthonormal systems on compact Riemannian manifolds in the non-sharp admissible region of exponents, covering wave, Klein-Gordon, and frac…

Non-Hermitian spectral universality at critical points

Giorgio Cipolloni, LÃ¡szlÃ³ ErdÅs, Hong Chang Ji

For general large non-Hermitian random matrices $X$ and deterministic normal deformations $A$ , we prove that the local eigenvalue statistics of $A + X$ close to the critical edge poi…

On the spectral edge of non-Hermitian random matrices

Andrew Campbell, Giorgio Cipolloni, LÃ¡szlÃ³ ErdÅs +1

For general non-Hermitian random matrices $X$ and deterministic deformation matrices $A$ , we prove that the local eigenvalue statistics of $A + X$ close to the typical edge points of…
