Quick Plan

  • Talk about some interesting properties of knots:
    1. Can it be unknotted in less than 3 crossing changes?
    2. Does it bound a disk in the 4-ball?
  • Briefly mention a few other interesting properties of knots:
    1. Is it the closure of a braid on at most 6 strands?
    2. Does it have a projection with less than 23 crossings?
    3. Does it have an alternating projection?
    4. Is it algebraic?
