ε-熵的新方法及其与Kolmogorov ε-熵的比较
New approach to Epsilon-entropy and Its comparison with Kolmogorov's Epsilon-entropy
摘要:
Kolmogorov引入了ε-熵的概念来分析经典连续系统中的信息。几何集合的分形维数是由Mandelbrot提出来的,它是分析几何集合复杂性的一个新判据。为了刻画一般量子系统的混沌性质,本文作者引入了一般量子系统的态的ε熵和分形维数。本文证明了态的ε熵包含Kolmogorov ε熵,态的分形维数描述了高斯测度的分形结构。
英文摘要:
Kolmogorov introduced a concept of Epsilon-entropy to analyze information in classical continuous system. The fractal dimension of geometrical sets was introduced by Mandelbrot as a new criterion to analyze the complexity of these sets. The Epsilon-entropy and the fractal dimension of a state in general quantum system were introduced by one of the present authors in order to characterize chaotic properties of general states. In this paper, we show that Epsilon-entropy of a state includes Kolmogorov Epsilon-entropy, and the fractal dimension of a state describe fractal structure of Gaussian measures.
