Abstract:

We define a ï¿½dualï¿½ of a quadruplet of points in

in a conformal geometric way. We show that the dual of a dual quadruplet coincides with the original one. We also show that the cross ratio of the dual quadruplet is equal to the complex conjugate of that of the original one.

Keywords and phrases:

dual, conformal geometry, cospherical.
