Non-Hermitian spectral universality at critical points

Abstract

For general large non-Hermitian random matrices XX and deterministic normal deformations AA, we prove that the local eigenvalue statistics of A+XA+X close to the critical edge points of its spectrum are universal. This concludes the proof of the third and last remaining typical universality class for non-Hermitian random matrices, after bulk and sharp edge universalities have been established in recent years.
