Modellizzazione dei sistemi complessi: un’introduzione metodologica

Abstract

We propose a methodological introduction in modeling dynamical systems for didactical aims. Firstly, we recall the deterministic paradigm in the description of natural phenomena, typical of classical physics and mathematically described by using differential equations. With the discovery of the deterministic chaos, the randomness of the motion is accepted and the description of phenomena is performed using stochastic differential equations. Finally, a special attention is devoted to the case of complex systems.
