Almost sure convergence and second moments of geometric functionals of fractal percolation

We determine almost sure limits of rescaled intrinsic volumes of the construction steps of fractal percolation in ${\mathbb{R}}^d$ for any dimension $d\ge 1$. We observe a factorization of these limit variables which allows, in particular, to determine their expectations and covariance structure. We also show convergence of rescaled expectations and variances of the intrinsic volumes of the construction steps to expectations and variances of the limit variables and give rates for this convergence in some cases. These results significantly extend our previous work that addressed only limits of expectations of intrinsic volumes.
