Self-organization of Active Surfaces — •Frank Jülicher — Max-Planck Institut für Physik komplexer Systeme, Nöthnitzerstr. 38, 01187 Dresden

Biological cells are active systems and exhibit complex dynamic behaviors such as cell division, cell polarity establishment and cell locomotion. Such dynamic processes emerge from the collective interplay of many molecular components far from thermodynamic equilibrium. Active molecular processes such as the force generation of molecular motors along filaments of the cytoskeleton transduce chemical free energy to generate movements and mechanical work. I will discuss the self-organization of active surfaces in different geometries as models for the dynamics of the cell cortex. Self-organised active surfaces provide minimal models for the generation of shape and the emergence of dynamic patterns in basic cellular processes.
