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), represents the rate at which 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 exist, we define Dr(μ)\underline{D}_r(\mu) and Dr(μ)\overline{D}_r(\mu) as the lower and the upper quantization dimensions of μ\mu of order rr, respectively. In this paper, we investigate the quantization dimension of the condensation measure μ\mu associated with a condensation system ({Sj}j=1N,(pj)j=0N,ν).(\{S_j\}_{j=1}^N, (p_j)_{j=0}^N, \nu). We provide two examples: one where ν\nu is an infinite discrete distribution on R\mathbb{R}, and one where ν\nu is a uniform distribution on R\mathbb{R}. For both the discrete and uniform distributions ν\nu, we determine the optimal sets of nn-means, and calculate the quantization dimensions of condensation measures μ\mu, and show that the Dr(μ)D_r(\mu)-dimensional quantization coefficients do not exist. Moreover, we demonstrate that the lower and upper quantization coefficients are finite and positive.
