The unique non self-referential q-canonical distribution and the physical temperature derived from the maximum entropy principle in Tsallis statistics
The maximum entropy principle in Tsallis statistics is reformulated in the
mathematical framework of the q-product, which results in the unique non
self-referential q-canonical distribution. As one of the applications of the
present formalism, we theoretically derive the physical temperature which
coincides with that already obtained in accordance with the generalized zeroth
law of thermodynamics.Comment: The title, representations and references are revise
Large deviation estimates involving deformed exponential functions
We study large deviation properties of probability distributions with either
a compact support or a fat tail by comparing them with q-deformed exponential
distributions. Our main result is a large deviation property for probability
distributions with a fat tail.Comment: typos corrected, some addtional explanations, version to appear in

-generalization of Gauss' law of error
Based on the -deformed functions (-exponential and
-logarithm) and associated multiplication operation (-product)
introduced by Kaniadakis (Phys. Rev. E \textbf{66} (2002) 056125), we present
another one-parameter generalization of Gauss' law of error. The likelihood
function in Gauss' law of error is generalized by means of the
-product. This -generalized maximum likelihood principle leads
to the {\it so-called} -Gaussian distributions.Comment: 9 pages, 1 figure, latex file using elsart.cls style fil
Multiplicative duality, q-triplet and (mu,nu,q)-relation derived from the one-to-one correspondence between the (mu,nu)-multinomial coefficient and Tsallis entropy Sq
We derive the multiplicative duality "q1/q" and other typical mathematical
structures as the special cases of the (mu,nu,q)-relation behind Tsallis
statistics by means of the (mu,nu)-multinomial coefficient. Recently the
additive duality "q2-q" in Tsallis statistics is derived in the form of the
one-to-one correspondence between the q-multinomial coefficient and Tsallis
entropy. A slight generalization of this correspondence for the multiplicative
duality requires the (mu,nu)-multinomial coefficient as a generalization of the
q-multinomial coefficient. This combinatorial formalism provides us with the
one-to-one correspondence between the (mu,nu)-multinomial coefficient and
Tsallis entropy Sq, which determines a concrete relation among three parameters
mu, nu and q, i.e., nu(1-mu)+1=q which is called "(mu,nu,q)-relation" in this
paper. As special cases of the (mu,nu,q)-relation, the additive duality and the
multiplicative duality are recovered when nu=1 and nu=q, respectively. As other
special cases, when nu=2-q, a set of three parameters (mu,nu,q) is identified
with the q-triplet (q_{sen},q_{rel},q_{stat}) recently conjectured by Tsallis.
Moreover, when nu=1/q, the relation 1/(1-q_{sen})=1/alpha_{min}-1/alpha_{max}
in the multifractal singularity spectrum f(alpha) is recovered by means of the
(mu,nu,q)-relation.Comment: 20 page
