Abstract

For a selfadjoint element x in a tracial von Neumann algebra and α=δ0(x)\alpha = \delta_0(x) we compute bounds for Hα(x),\mathbb H^{\alpha}(x), where Hα(x)\mathbb H^{\alpha}(x) is the free Hausdorff α\alpha-entropy of x.x. The bounds are in terms of R2Dlogyzdμ(y)dμ(z)\int \int_{\mathbb R^2 -D} \log |y-z| d\mu(y) d\mu(z) where μ\mu is the Borel measure on the spectrum of x induced by the trace and DR2D \subset \mathbb R^2 is the diagonal. We compute similar bounds for the free Hausdorff entropy of a free family of selfadjoints.
