Dissertation note: Tesi di diploma di 1° livello per la Classe delle Scienze Sperimentali Diploma di 1° livello Scuola Superiore di Catania, Catania, Italy 2009 A.A. 2007/2008 Abstract: The dissemination of opinions and cultural features is a complex phenomenon that concerns the formation of large social systems and has its roots on local interactions. In particular, it is easy to realize, by looking at our everyday life, that people are continuously confronted with a limited number of positions on a specific issue, for instance the political party to vote, the favorite songs, the football team to support. Besides, the position of each individual about each cultural feature is not permanent. On the contrary, this position is affected by those other people being in contact with the individual. To formalize this cultural dissemination process in a social system we make use of the celebrated Axelrod model (1997). In the Axelrod model, human opinions and culture are respectively treated as a variable or a set of variables. In this sense, adequate sets of mathematical rules can be used to describe the mechanisms responsible for the evolution and changes of culture as the result of the agreement or disagreement among individuals.
