The Emergence Of Groups In The Evolution Of Friendship Networks

Friendship networks usually show a certain degree of segmentation: subgroups of friends. The explanation of the emergence of such groups from initially dyadic pair friendships is a diflicult but important problem. In this paper we attempt to provide a first contribution to the explanation of subgroup formation in friendship nelworks by using the LS set as a definition for a friendship group. Wc construct a dynamic individual oriented model of friendship formation and provide preliminary simulation results that give an idea of how to continue the process of explaining group formatio
