Effective Gaps between singular values of non-stationary matrix products subject to non-degenerate noise
Sam Bednarski, Jonathan DeWitt, Anthony Quas
We study the singular values and Lyapunov exponents of non-stationary random matrix products subject to small, absolutely continuous, additive noise. Consider a fixed sequence of m…

Lyapunov exponents of orthogonal-plus-normal cocycles
Sam Bednarski, Anthony Quas
We consider products of matrices of the form where is a sequence of orthogonal matrices and has independent standard normal entries and the $…
