A large number of surfaces/interfaces and biological organelles, such as vesicles and helical (lipid) ribbons, are described by elastic, deformable surfaces with a local and/or global curved geometry. They show an amazing variety of shapes of different symmetry and topology, under different temperature, osmotic pressure, and chemical concentration conditions. In addition, processes, such as lipid phase separation, are known to couple to local curvature. Enclosed membranes contain fluids and thus a coupling of curved manifold elasticity to hydrodynamics becomes very important. Other topics of current interest include DNA tangle equations based on knot theory, pearling instability in fluid microtubules and twisted elastic filaments in viscous fluids. In this mnisymposium, the speakers will discuss the study of electrorheological and magnetorheological fluids contained in deformable curved geometries such as vesicles, microtubles and tori.Organizers: Avadh Saxena
