Abstract

For a given r(0,+)r\in (0, +\infty), the quantization dimension of order rr, if it exists, denoted by Dr(μ)D_r(\mu), of a Borel probability measure μ\mu on Rd{\mathbb R}^d represents the speed how fast the nnth quantization error of order rr approaches to zero as the number of elements nn in an optimal set of nn-means for μ\mu tends to infinity. If Dr(μ)D_r(\mu) does not exists, we call Dr(μ)\underline D_r(\mu) and Dr(μ)\overline D_r(\mu), the lower and upper quantization dimensions of μ\mu of order rr. In this paper, we estimate the quantization dimension of condensation measures associated with condensation systems ({fi}i=1N,(pi)i=0N,ν)(\{f_i\}_{i=1}^N, (p_i)_{i=0}^N, \nu), where the mappings fif_i are bi-Lipschitz and the measure ν\nu is an image measure of an ergodic measure with bounded distortion supported on a conformal set. In addition, we determine the optimal quantization for an infinite discrete distribution, and give an example which shows that the quantization dimension of a Borel probability measure can be positive with zero quantization coefficient.
