Every point on the unit circle C intersects the sphere K, and hence they are all mapped to themselves. The unique plane intersecting C is exactly C, hence when Σ is inverted through K, it is mapped exactly to C.

http://torus.math.uiuc.edu/jms/Papers/isama/color/opt2.htm WebGiven a circle or sphere of radius \(r\), inversion sends a point \(P\) to a point \(P'\) where \(OP \cdot OP' = r^2\) and the two points lie on the same line going through the center of the inverting sphere. Note that points on the boundary are fixed. In its most basic definition, the inversion map is not defined at the center of the sphere. kirst conversion kitWebMay 5, 2024 · A point P inside a sphere can be inverted with respect to the spherical surface to another point P' outside.

WebSep 4, 2024 · The inversion in a sphere is defined the same way as we define the inversion in a circle. Formally, let Σ be the sphere with the center O and radius r. The inversion in Σ of a point P is the point P ′ ∈ [OP) such that OP ⋅ OP ′ = r2. In this case, the sphere Σ will be called the sphere of inversion and its center is called the center of inversion.
