Examples of sub-bundles

53 Views Asked by At

I was wondering if anyone has any examples of sub-bundles of a bundle. Intuitively, I think that a Möbius strip is a sub-bundle of a torus since you can think of a torus as a circle that you attach discs to, while a Möbius strip is a circle that you attach lines to. The lines can be picked so that they are submanifolds of the discs. Am I correct?
