DESCRIPTION:Title: <a href="https://researchseminars.org/talk/PIMS_GAP/13/
 ">Random knotting and linking</a>\nby Puttipong Pongtanapaisan (University
  of Saskatchewan) as part of PIMS Geometry / Algebra / Physics (GAP) Semin
 ar\n\nLecture held in THORV 124.\n\nAbstract\nBack in the old days\, befor
 e the invention of Apple Wireless Airpods\, people were more familiar with
  the tendency of the headphones in their pockets to become knotted. It see
 ms natural to expect that the probability that a random curve is tangled i
 ncreases with its length. In fact\, Frisch\, Wasserman\, and Delbrück con
 jectured that sufficiently long ring polymers will be knotted with high pr
 obability. In this talk\, I will discuss some models where the conjecture 
 is known to be true\, including a setting that I investigated with Jeremy 
 Eng\, Chris Soteros\, and Rob Scharein. Topological techniques used in the
  proofs such as finite-type invariants will also be discussed.\n\nHybrid d
 elivery (in person on University of Saskatchewan campus and via Zoom).\n
