Teaching activities

Complex Dynamic Systems

The course presents an introduction to the different tools for the analysis of comlpex systems. In particular, the theory of nonlinear dynamic systems is tackled, including qualitative analysis of nonlinear ordinary differential equations and bifurcation theory. Morever, the mathematical tools for the description and analysis of complex networks are presented. Algorithms for the simulation of complex dynamics, such as limit cycle oscillations and chaotic behavior, as well as for the visualiztion and statistical analysis of graphs are introduced. Several examples of complex systems in discrete and continuous time with application to population dynamics, economics, social science, ecological and biological systems are discussed. 

 

Game Theory

 

The course is aimed at introducing the methodological bases of game theory and evolutionary game theory. In the first part of the course, the concept of game is introduced as the strategic decision of a player. The game outcome depends on the choices of other players which share the same information. In the second part of the course, the evolutionary game theory is introduced. In this case the game is repeated in a large population of players. The ensemble of the decisions will affect the future distribution of strategies inside the population. Finally, the course provides several examples and applications in socio-economic, environmental and engineering fields.

Research

Evolutionary Games on Networks

Development of mathematical models, grounded on evolutionary game equations, where players are located at the nodes of a network of connections. The models describe decision mechanisms of a finite set of players under replication, selection pressure and social influence. An extended version of the model describes the continuous dynamics of individuals or groups interacting each other under a baseline prisoner's dilemma game appropriately modified with the aim of accounting for a self-regulative inertial factor which favours the onset of cooperation. The extended model well explains propensity to cooperation in European Countries under the assumption that individuals are driven by homophily, endogamy and civicness and shows formally that strong cooperation within familistic cliques induces a decrease of cooperation at global level. 

The model has been also applied to investigate the formation of networks among the members of a microbial population as a response to hostile environments. A further application to neuroscience showed a good performance of the evolutionary game equations on networks in reproducing spontaneous brain behavior.

Biophysical Systems Analysis and Behavior

In the field of monitoring and analysing the environmental status of water systems, we have developed tools for decision support and real-time water monitoring based on low cost unmanned surface vehicles and mathematical modeling.

A bounded rationality model of spontaneous remission from addctive behavioral patterns has been designed. We showed that natural recovery from addiction without external committments is feasible by assuming enough high level of awareness of individuals.

Nonlinear time series analysis

Nonlinear time series analysis has been applied to the study of brain patterns with particular attention to the level of hypnotizability of subjects. The research has been conducted by analyzing the EEG time series recorded in several regions of the scalpo of resting state, not hypnotized subjects.

Application of nonlinear time series analysis to the reconstruction of embedded state spaces and detection of critical regimes in complex systems. The methodology allowed the identification of structurally different regimes, e.g. stable and unstable spiral waves, in the Complex Ginzburg-Landau equation and in biochemical reaction-diffusion systems undergoing Turing instabilities and in presence of roughness in the boundaries.
