In the second part of this study and similarly with part one, the nonlinear
analysis of the solar flares index is embedded in the non-extensive statistical
theory of Tsallis [1]. The triplet of Tsallis, as well as the correlation
dimension and the Lyapunov exponent spectrum were estimated for the SVD
components of the solar flares timeseries. Also the multifractal scaling
exponent spectrum, the generalized Renyi dimension spectrum and the spectrum of
the structure function exponents were estimated experimentally and
theoretically by using the entropy principle included in Tsallis non extensive
statistical theory, following Arimitsu and Arimitsu [2]. Our analysis showed
clearly the following: a) a phase transition process in the solar flare
dynamics from high dimensional non Gaussian SOC state to a low dimensional also
non Gaussian chaotic state, b) strong intermittent solar corona turbulence and
anomalous (multifractal) diffusion solar corona process, which is strengthened
as the solar corona dynamics makes phase transition to low dimensional chaos:
c) faithful agreement of Tsallis non equilibrium statistical theory with the
experimental estimations of i) non-Gaussian probability distribution function,
ii) multifractal scaling exponent spectrum and generalized Renyi dimension
spectrum, iii) exponent spectrum of the structure functions estimated for the
sunspot index and its underlying non equilibrium solar dynamics. e) The solar
flare dynamical profile is revealed similar to the dynamical profile of the
solar convection zone as far as the phase transition process from SOC to chaos
state. However the solar low corona (solar flare) dynamical characteristics can
be clearly discriminated from the dynamical characteristics of the solar
convection zone.Comment: 21 pages, 11 figures, 1 table. arXiv admin note: substantial text
