Dynamics of Curves and Filaments

The motion and dynamical behavior of curves and filaments provide excellent models for physical problems ranging from DNA conformation (10-8 meters) to motion of solar flux tubes and sunspot formation (108 meters), with many more relevant examples in between. Although a classical subject, recent advances in experimental, computational, and analytical techniques have brought increased attention to the study of the dynamics of curve and filament systems. In this minisymposium a thin cross-section of these new methods and results will be presented with an emphasis on applications to physical systems. The purpose of this minisymposium is to acquaint the general applied math community with some of the extensive recent work on curve dynamics, particularly curves with twist, and its relation to physical systems.
