 ">Applications of band surgery on knots and links</a>\nby Koya Shimokawa (
 Ochanomizu University - Japan) as part of GEOTOP-A seminar\n\n\nAbstract\n
 We consider local moves of knots and links\, called band surgeries. A band
  surgery usually changes the topology of knots and links. Signatures\, Jon
 es polynomials\, and other link invariants can be used to show the absence
  of band surgery between a given pair of links. A band surgery has been us
 ed for establishing mathematical models of DNA recombination and anti-para
 llel reconnection of vortex knots and links. In this talk\, we discuss app
 lications of results of band surgeries to the unlinking of DNA links by si
 te-specific recombination and to the untying of vortex knots by anti-paral
 lel reconnection.\n
