Course description   
In 1955 E. Wigner had the revolutionary vision that energy level statistics of heavy nuclei are universal, and suggested Random (Hermitian) Matrices as a simple toy model to prove this phenomenon in a mathematical rigorous way. This is known as Wigner-Dyson-Gaudin-Mehta (WDM) conjecture. Since then, it has been conjectured that random matrix statistics are actually much more universal, appearing in number theory (Montgomery conjecture for Riemann zeta function), dynamical systems (Bohigas-Giannoni-Schmidt conjecture), and neural networks.

In this course we will briefly present these conjectures and give a short overview of interesting open questions in random matrix theory. Then we will walk through a new short proof of the WDM conjecture that uses recently developed techniques relying on
1) Dynamical proof of local laws (i.e. law of large numbers for resolvents).
2) Optimal relaxation of the Dyson Brownian motion.
 
This course is designed as an introduction to the fundamentals of random matrix theory, which can be useful for diverse questions in mathematical physics, machine learning, and number theory.
