摘要:In this paper, we introduce a new notion called Minkowski measure for a class of metric spaces, which is closely related to the box dimension of the space. If E is a self-similar set satisfying the open set condition, then the Hasudorff measure restricted to E is a Minkowski measure. We show that the Lalley-Gatzouras type self-affine sponges always admit Minkowski measures. Moreover, we show that if a metric space is totally disconnected and possesses Minkowski measure, then the multi-fractal spectrum of the Minkowski measure is a Lipschitz invariant.
