Query: Axioms and uniqueness theorem for Tsallis entropy   The Shannon-Khinchin axioms for the ordinary information entropy are
generalized in a natural way to the nonextensive systems based on the concept
of nonextensive conditional entropy, and a complete proof of the uniqueness
theorem for the Tsallis entropy is presented.
