Public Lecture im Rahmen des 7th Vienna Central European Seminar on Particle Physics and Quantum Field Theory Mitschnitt einer Veranstaltung am Freitag, dem 26. November 2010 im Lise-Meitner-Hörsaal der Fakultät für Physik Begrüßung und einleitende Worte: Helmuth Hüffel (Fakultät für Physik der Universität Wien) Abstract: Complex Networks have become a quite successful approach to analyse the structure and dynamics of systems with many interacting elements. These elements (often denoted as agents) are represented by the nodes of a network, whereas their interaction is described by the links between nodes. Statistical physics has mostly focused on the topology of such networks, emphasizing the fact that interaction occurs not necessarily via a mean field or on a regular lattice. Instead, the heterogeneity in interaction plays an important role to understand the growth of real networks. The talk will present different examples of growing complex networks ranging from Open Source Software to Economic Networks. It addresses the impact of topology, weighted links, dynamics of links and nodes on the emergence of systemic properties, such as robustness or adaptivity. Frank Schweitzer ist Professor für Systemgestaltung an der ETH Zürich. Kapitel Titel Position --------------------------------------------------------------------- 1. Vorspann 00:00:00 2.
