Abstract: In this talk, we consider the spectral radius of a large random matrix with independent and identically distributed entries. We show that its typical size is given by a precise and universal three-term asymptotics with an optimal error term, beyond the radius of the celebrated circular law. A similar three-term asymptotics also holds true for the rightmost eigenvalue with slightly different coefficients.
Based on joint work with Giorgio Cipolloni, Laszlo Erdos, and Dominik Schroder.
