Maximum of the characteristic polynomial of random Jacobi matrices

Fanny Augeri, Ofer Zeitouni

We compute the second order asymptotics of the maximum of the absolute value of the log-characteristic polynomial of random Jacobi matrices whose coefficients satisfy some exponent…

The Liouville model in the phase: coupling and extreme values

Michael Hofstetter, Ofer Zeitouni

We establish a strong coupling between the Liouville model and the Gaussian free field on the two dimensional torus in the phase , such that the difference of t…

The maximum of the two dimensional Gaussian directed polymer in the subcritical regime

Clément Cosco, Shuta Nakajima, Ofer Zeitouni

We study the maximum of the partition function of the two dimensional (subcritical) Gaussian directed polymer over an box. We show that $ϕ_N^*/\log…

Tightness of the maximum of Ginzburg-Landau fields

Florian Schweiger, Wei Wu, Ofer Zeitouni

We consider the discrete Ginzburg-Landau field with potential satisfying a uniform convexity condition, in the critical dimension , and prove that its maximum over boxes of si…

The shape of the front of multidimensional branching Brownian motion

Yujin H. Kim, Ofer Zeitouni

We study the shape of the outer envelope of a branching Brownian motion (BBM) in , . We focus on the extremal particles: those whose norm is within of…

A CLT for the characteristic polynomial of random Jacobi matrices, and the GE

Fanny Augeri, Raphael Butez, Ofer Zeitouni

We prove a central limit theorem for the logarithm of the characteristic polynomial of random Jacobi matrices. Our results cover the GE models for .
