We introduce the notion of a random matrix-valued multiplicative function, generalizing Rademacher random multiplicative functions to matrices. We provide an asymptotic for the second moment based on a linear recurrence property for Hilbert-Schmidt norms of sucessive products of random matrices. Moreover, we provide upper bounds for the higher even moments related to the generalized joint spectral radius.

A procedure for approximating the joint spectral radius of a finite set of matrices with arbitrary high accuracy based on semidefinite liftings and it is proved that a widely used approximation based on common quadratic Lyapunov functions (or on ellipsoid norms) has relative accuracy $1/\sqrt m$, where $m$ is the number ofMatrices and $n$ is their size.

We estimate some sums of the shape S(Xβ1,…, Xβm): = [sum ] 1 [les ] d1 [les ] Xβ1… [sum ]1 [les ] dm [les ] Xβm ƒ(d1,…, dm), when m ∈ $\Bbb N$ and f is a nonnegative arithmetical function. We relate
