[BOOK][B] One-Dimensional Ergodic Schrödinger Operators: I. General Theory
The theory of one-dimensional ergodic operators involves a beautiful synthesis of ideas from
dynamical systems, topology, and analysis. Additionally, this setting includes many models …

On the generalization of learning algorithms that do not converge
Generalization analyses of deep learning typically assume that the training converges to a
fixed point. But, recent results indicate that in practice, the weights of deep neural networks …

A regularity method for lower bounds on the Lyapunov exponent for stochastic differential equations
We put forward a new method for obtaining quantitative lower bounds on the top Lyapunov
exponent of stochastic differential equations. Our method combines (i) a new identity …

Parametric Furstenberg theorem on random products of SL (2, R) matrices
We consider random products of SL (2, R) matrices that depend on a parameter in a non-
uniformly hyperbolic regime. We show that if the dependence on the parameter is monotone …
