Sphere eversion

Web9. sep 2024 · In the late 1950’s Steve Smale proved a theorem that implies among other things that one can evert the sphere, i.e. that there is a continuous path in the space of smooth maps from to from the canonical immersion (the identity if the unit Eudlidean sphere) to the antipodal one (minus the identity), such that these maps are all immersions. WebThe surface has only one side, like a Klein bottle, but is topologically distinct in how the surface is self-connected. This can be turned into a sphere eversion by prying the surface apart, a bit like prying apart a Möbius strip made of toilet paper. kuroyaki • 11 yr. ago
