Mobius strip with constant negative curvature

390 Views Asked by At

Is there any simple model of the Mobius strip with a constant negative Gaussian curvature? There is an example on Wikipedia (https://en.wikipedia.org/wiki/M%C3%B6bius_strip#Open_M%C3%B6bius_band), but it only states that it can "easily" be seen that it is in fact homeomorphic to a Mobius strip, and I don't see it at all.
