Abstract: This paper studies the evolution of the distribution of opinions in apopulation of individuals in which there exist two distinct subgroups ofhighly-committed, well-connected opinion leaders endowed with a strongconvincing power. Each individual, located at a vertex of a directed graph, ischaracterized by her name, the list of people she is interacting with, herlevel of awareness, and her opinion. Various temporal evolutions according todifferent local rules are compared in order to find under which conditions theformation of strongly polarized subgroups, each adopting the opinion of one ofthe two groups of opinion leaders, is favored.
