4D-knots: what are they? Can we visualize them?
Are there interesting math problems about them?
The film is divided in three parts:
- Knots in 3D. Here we introduce notation and concepts for usual knots. 3D-knots are represented in 2D.
- Knotted surfaces in 4D. Parallel of part 1, in one dimension more! 4D-knots are represented as 3D objects (on a 2D screen, alas!).
- Ribbon knotted surfaces. A particular type of 4D-knots, maybe the “simplest” ones to describe. They have different representations and analyzing them we meet open questions in maths!
