21. On the mathematics of the one-dimensional Hegselmann-Krause model
Sammanfattning : This thesis contains three papers, which all in different ways concern the asymptotics of the Hegselmann-Krause model in opinion dynamics. In this model a set of conformist agents repeatedly and synchronously replace their real-valued opinions by the average of those opinions that are within unit distance of their own. LÄS MER
22. Tensions of extensions : adverse effects of brand extension within consumer relationships
Sammanfattning : Imagine how you would react if you learned that your favorite singer was recording new music in a style far from that which you have come to love. Perhaps you would disapprove.

24. Interacting particle systems for opinion dynamics: the Deffuant model and some generalizations
Sammanfattning : In the field of sociophysics, concepts and techniques taken from statistical physics are used to model and investigate some social and political behavior of a large group of humans: their social network is given by a simple graph and neighboring individuals meet and interact in pairs or small groups. Although most of the established models feature rather simple microscopic interaction rules, the macroscopic long-time behavior of the collective often eludes an analytical treatment due to the complexity, which stems from the interaction of the large system as a whole.

25. Dynamic Interactions : National Political Parties, Voters and European Integration
Sammanfattning : This thesis consists of an introduction and four self-contained papers, designated I-IV, which extend previous research on national political parties and voters in Western Europe. More specifically, the issues addressed are parties’ positions and voters’ opinions on European integration and their dynamic interactions, i.e. LÄS MER
