Many applications of nonextensive statistical mechanics have been studied:
turbulence, anomalous diffusion, economy, cosmic ray fluxes, bacterial development,
selforganized criticality, selfgravitating systems..
All these phenomena share longrange correlations in space/time,
or fractal boundary conditions, or some mechanism creating
a scaleinvariant hierarchical structure. Such phenomena
occur in nonlinear dynamical systems, when the Lyapunov factors
approach zero and departure from
initial conditions is no longer exponential.
At the boundary of chaos, generalisations of the entropy, for instance
in terms of qentropy, to take into account its pseudoextensivity,
have encountered success in dealing with these nonlinear
systems.
The meeting will focus on recent progress in
particular on statistical mechanics of
selfgravity, turbulence and stock markets.
The main topics will be:
 Statistical mechanics of collisionless stellar systems
 Interstellar medium, selfgravity and fractal structure
 Turbulence, chaos, and generalized thermodynamics
 Statistical mechanics of stock markets
