The main goal of this Workshop is surveying the relevance of pseudochaos for various research domains in mathematics and physics. By pseudochaos it is usually meant the irregular behavior characterizing the unpredictable evolution of dynamical systems in the absence of the Lyapunov instability mechanism. Far from being a mere mathematical curiosity, pseudochaos has appeared in an astonishingly wide range of models, including spatially extended systems (e.g., coupled map lattices), finite and infinite polygonal billiards, cellular automata, neural networks etc. The many progresses made in the understanding of pseudochaos have unveiled its importance for the foundations of Statistical Mechanics (validity of transport equations, role of ergodicity), for the crossover from discrete to continuous descriptions, and even for the semi-classical limit of quantum mechanics.
In the last decade an increasing community of researchers had to deal with pseudochaos while trying to tackle problems in basic science as well as in applications and experiments. Actually, beyond its conceptual interest, pseudochaos provides an effective tool for analyzing and understanding many practical problems like transport in nanosystems, neural synchronization and plasticity, cryptography and adaptive computational procedures.
This is the main reason why the Workshop aims also at collecting scientists from different research areas sharing a common interest for pseudochaos and its applications.
A series of lectures will provide an introduction to the main topics of the Workshop:
• Normal and anomalous transport
• Non chaotic and weakly chaotic classical and quantum dynamical systems
• Stable chaos, disturbance propagation, synchronization
• Ballistic, diffusive and directed transport in quantum systems
• Measures of complexity for classical and quantum non chaotic systems
