title: Changes in the entropy and the Tsallis difference information during spontaneous decay and self-organization of nonextensive systems
abstract: A theoretical-information description of self-organization processes during stimulated transitions between stationary states of open nonextensive systems is presented. S/sub q/- and I/sub q/-theorems on changes of the entropy and Tsallis difference information measures in the process of evolution in the space of control parameters are proved. The entropy and the Tsallis difference information are derived and their new extreme properties are discussed
keyphrases: entropy Tsallis difference information spontaneous decay self-organization nonextensive systems stimulated transitions information measures control parameters nonextensive statistical mechanics
