In this talk we examine when these sewn ribbon complexes embed in
3-space. We give several characterizations of these spatial ribbons
complexes. We also consider the theoretical and algorithmic
implications of our characterizations. The problem seems to lie right
on the boundary (assuming there is one) between polynomial and
NP-complete problems.
Tea. High tea will be served at 3:30 pm in the Lounge.
Emmy's. Certain refreshments will be available at Emmy's after the talk.
