| Résume | An old question of Halpern and Weaver asks what is the smallest aspect
ratio of a Moebius band made out of paper that can be isometrically
embedded in ℝ3. In my talk I will recall previous
results about this, and sketch a proof of my improved lower bound for
the answer. I will also explain how I reduced the whole conjecture to
showing that a handful of complicated algebraic expressions are
positive. Unfortunately, these expressions are too complicated for me
to figure out. |
