Meaning of non-extensive entropies in Micro-Macro duality

The purpose of this presentation is to clarify the universal meaning of generalized non-extensive entropies and/or statistics based on Tsallis entropy from the viewpoint of Micro-Macro duality. What plays here the most important roles is the notions of scales and scaling transformations which will be seen to be related closely to the main themes of this workshop, generalized non-extensive entropies and/or statistics and the information-geometrical structures of the classifying spaces.
