Llavinia replied to the thread Graduate Hopf fibration of 3-sphere.Right. BTW: Your answer proves that the Klein bottle can be embedded in R^4. So for two linked fibers in the 3 sphere, is the worry...

Llavinia replied to the thread Graduate Hopf fibration of 3-sphere.OK. So how would you move two linked loops in R^3 off of each other into R^4 without them crossing over each other? How would you move...

Llavinia replied to the thread Graduate Hopf fibration of 3-sphere.As an example, consider the equator of the three sphere, the circle in S^3 whose third and fourth coordinates are both zero. It divides...

Llavinia replied to the thread Graduate Hopf fibration of 3-sphere.What are your thoughts on this?

Llavinia replied to the thread Graduate Hopf fibration of 3-sphere.@Hornbein Intuitively, in Euclidean 3 space, two non-intersecting closed loops are linked if they cannot be separated without...

Llavinia replied to the thread Undergrad About the definition of topological manifold using closed sets.A way to construct topological manifolds from closed subsets of Euclidean space is through triangulations. For example, one can imagine...
