Abstract:

Reconnection is a fundamental event in many area of science,
including interaction of fluid vortices and flux tubes in
fluid mechanics and magnetohydrodynamics, and site-specific
recombination in DNA.  This talk will discuss the mathematical
similarities between reconnection events in biology and physics, and
the relationship between iterated reconnection and curve topology.  In
particular, the reconnection cascade from (2,2k+1) torus knots to
(2,2k) torus links to the unlink of two unknotted circles observed in
DNA is also observed in fluid vortex reconnections.
