I will discuss a problem that appeared on MathOverflow and its solution by the user “Fedja”. The result we will demonstrate is that if T is subset of the reals with Hausdorff dimension exceeding ½, then there is a positive probability that a standard...

We consider an arbitrary sequence of d*d matrices (A_n) of norm at most 1 and subject them to noiselike perturbations of size epsilon. We show that the perturbed system has simple Lyapunov spectrum (no repeated exponents) and discuss universal bounds...

Given a collection of points S in a metric space and a probability p in (0,1), one can make a random graph by independently joining any pair of points in S that are less than 1 apart by an edge with probability p; and no edge with probability 1-p...

Lyapunov exponents and Oseledets spaces are a rough analogue of eigenvalues and eigenspaces for stationary products of matrices (or operators). We are interested in the stability or otherwise of these exponents and spaces when the family of matrices...
