Anderson's model in 1 dimension has been studied since the 80's and the location is well understood. Here I propose a new formula for the construction of the eigenvectors which makes the link with the products of independent random matrices. In particular, I show that, with a adapted scaling, eigenvectors behave as the exponential of a Brownian process with a drift, the drift corresponding to the classical localization result. This result is known for the product of independent random matrices but at our knowledge had not been generalized to Anderson's model.

Topological recursion (TR) arose from random matrix models and was promoted to a mathematical theory in 2007. It can be thought as an implementable algorithm which takes as input an object called spectral curve and produces as output the infinite list of numbers which are solution to some enumerative problem. TR is by now applied to Mirror Symmetry, String Theory, Gromov-Witten theory, Hurwitz theory, WKB analysis, Painleve equations, polynomial invariants of knots, Hitchin systems, and more. We will give some accessible example of how it works and what can generate. If time allows, we’ll dive into some conjectural connection with resurgence.
