DESCRIPTION:Arguably some of the most interesting phenomena in fluid dynam
 ics\, both from a mathematical and a physical perspective\, stem from the 
 interplay between a fluid and its boundaries. This talk will present some 
 examples of how boundary effects lead to remarkable outcomes.  Singulariti
 es can form in finite time as a consequence of the continuum assumption wh
 en material surfaces are in smooth contact with horizontal boundaries of a
  fluid under gravity. For fluids with chemical solutes\, the presence of b
 oundaries impermeable to diffusion adds further dynamics which can give ri
 se to self-induced flows and the formation of coherent structures out of s
 cattered assemblies of immersed bodies. These effects can be analytically 
 and numerically predicted by simple mathematical models and observed in 
 “simple” experimental setups. \n
