WebThe pinched torus is perhaps the simplest parameterization of the klein bottle in both three and four dimensions. It's a torus that, in three dimensions, flattens and passes through itself on one side. Unfortunately, in three dimensions this parameterization has two pinch points, which makes it undesirable for some applications. ... To make the "figure 8" or "bagel" immersion of the Klein bottle, one can start with a Möbius strip and curl it to bring the edge to the midline; since there is only one edge, it will meet itself there, passing through the midline. It has a particularly simple parametrization as a "figure-8" torus with a half-twist: for 0 ≤ θ < 2π, 0 ≤ v < 2π and r > 2. chemo for kidney cancer

Torus -- from Wolfram MathWorld

In mathematics, and especially topology and differential geometry, a pinched torus (or croissant surface) is a kind of two-dimensional surface. It gets its name from its resemblance to a torus that has been pinched at a single point. A pinched torus is an example of an orientable, compact 2-dimensional pseudomanifold. See more A pinched torus is easily parametrisable. Let us write g(x,y) = 2 + sin(x/2).cos(y). An example of such a parametrisation − which was used to plot the picture − is given by ƒ : [0,2π) → R where: See more Topologically, the pinched torus is homotopy equivalent to the wedge of a sphere and a circle.
