Quantization for a condensation system

Abstract

For a given $r \in (0, +\infty)$, the quantization dimension of order $r$, if it exists, denoted by $D_r(\mu)$, represents the rate at which the $n$th quantization error of order $r$ approaches to zero as the number of elements $n$ in an optimal set of $n$-means for $\mu$ tends to infinity. If $D_r(\mu)$ does not exist, we define $\underline{D}_r(\mu)$ and $\overline{D}_r(\mu)$ as the lower and the upper quantization dimensions of $\mu$ of order $r$, respectively. In this paper, we investigate the quantization dimension of the condensation measure $\mu$ associated with a condensation system $(\{S_j\}_{j=1}^N, (p_j)_{j=0}^N, \nu).$ We provide two examples: one where $\nu$ is an infinite discrete distribution on $\mathbb{R}$, and one where $\nu$ is a uniform distribution on $\mathbb{R}$. For both the discrete and uniform distributions $\nu$, we determine the optimal sets of $n$-means, and calculate the quantization dimensions of condensation measures $\mu$, and show that the $D_r(\mu)$-dimensional quantization coefficients do not exist. Moreover, we demonstrate that the lower and upper quantization coefficients are finite and positive.
