Lambert function and a new non-extensive form of entropy
收藏 引用
IMA JOURNAL OF APPLIED MATHEMATICS 2007年 第6期72卷 785-800页
作者: Shafee, Fariel Princeton Univ Dept Phys Princeton NJ USA
We propose a new way of defining entropy of a system, which gives a general form that is non-extensive like Tsallis entropy, but is linearly dependent on component entropies, like Renyi entropy, which is extensive. Th... 详细信息
