Tsallis熵稳定吗?

Is the Tsallis entropy stable?

James F. Lutsko, Jean Pierre Boon, Patrick Grosfils

摘要:

Tsallis熵是否是Lesche稳定的问题被重新讨论。有人认为,当物理平均值与护航概率计算,正确应用Lesche稳定性的概念,需要使用的护航概率。因此,如图所示,Tsallis熵是不稳定的,但热力学平均值是稳定的。我们进一步表明,Lesche稳定性以及热力学稳定性,可以得到如果均匀熵作为基础的非广延热力学制定。在这种方法中,护送分布作为二级结构自然出现。

英文摘要:

The question of whether the Tsallis entropy is Lesche-stable is revisited. It is argued that when physical averages are computed with the escort probabilities, the correct application of the concept of Lesche-stability requires use of the escort probabilities. As a consequence, as shown here, the Tsallis entropy is unstable but the thermodynamic averages are stable. We further show that Lesche stability as well as thermodynamic stability can be obtained if the homogeneous entropy is used as the basis of the formulation of non-extensive thermodynamics. In this approach, the escort distribution arises naturally as a secondary structure.
