Quantization of Random Homogeneous Self-Similar Measures

Abstract: In this article, we study a class of invariant measures generated by a random homogeneous self-similar iterated function system. Unlike the deterministic setting, the random quantization problem requires controlling distortion errors across non-uniform scales. For $r>0$, under a suitable separation condition, we precisely determine the almost sure quantization dimension $κ_r$ of this class, by utilizing the ergodic theory of the shift map on the symbolic space. By imposing an additional separation condition, we establish almost sure positivity of the $κ_r$-dimensional lower quantization coefficient. Furthermore, without assuming any separation condition, we provide a sufficient condition that guarantees almost sure finiteness of the $κ_r$-dimensional upper quantization coefficient. We also include some illustrative examples.
