*- 14:00 - 14:45   Complexity of near-Earth space plasma dynamics*

*Giuseppe Consolini*(INAF, Istituto di Astrofisica e Planetologia 
Spaziali, Roma, Italy)

The near-Earth space, the terrestrial magnetosphere, is a highly 
dynamical plasma system as a consequence of the variability of 
interplanetary space conditions. Over the years different modeling of 
the dynamics of this system in response to changes in the conditions of 
the interplanetary medium and the solar wind have been proposed: from 
chaos to forced and/or self organized criticality. In this talk a review 
of the most relevant results of the dynamics of the Earth's 
magnetosphere in terms of a complex system near a critical point is 
presented.


*- 14:45 - 15:30   One Thousand and One Dynamics - not that /F = ma/ was 
not enough*

*Massimo Materassi*(CNR-ISC, Istituto dei Sistemi Complessi, Florence, 
Italy)

Complex Systems are composite systems whose properties are emergent 
effects of the interactions among the subsystems composing them. In this 
presentation, I would like to briefly present some formalism useful for 
complex dynamical system study.


/Turbulent plasmas/give the opportunity of introducing stochastic and 
fractal formalism, while /Dissipative Systems/ are treated via 
metriplectic formalism. Last but not least, /Trophic Webs/, describing 
ecosystems, are an interesting meeting point for Biology, Conservation 
Laws and Network Theory.
