| Outline of Final Research Achievements |
We found the conjugate representations for constructing the statistical manifold associated with a family of the kappa-generalized exponential distributions. We have obtained the explicit expressions of the kappa-generalized geometrical quantities (e.g, Fisher metric, affine connections, divergence functions) which characterize the information geometric structures. We also showed that the kappa-statistical manifold is dually flat, which is an important feature in information geometry.
From these results we derive a kappa-generalization of the fluctuation-response relations, and pointed out the importance of an escort expectation value in addition to the conventional linear expectation.
