When is a Knot Not a Knot? When it is a Knotoid by Prof. Colin Adams, Wednesday, June 28, 1 – 1:50 pm, North Science Building 113, Wachenheim.
Abstract: Knotoids are a variation on knots where instead of tying a knot in a string and gluing the two loose ends together, we tie the knot but do not glue the loose ends together. Knotoids have been used to model proteins and a rich theory has developed around them. We will discuss what is known and what is still to know.
