Channel surfaces in Lie sphere geometry

Differential Geometry 2018-04-25 v1

Abstract

We discuss channel surfaces in the context of Lie sphere geometry and characterise them as certain Ω0\Omega_{0}-surfaces. Since Ω0\Omega_{0}-surfaces possess a rich transformation theory, we study the behaviour of channel surfaces under these transformations. Furthermore, by using certain Dupin cyclide congruences, we characterise Ribaucour pairs of channel surfaces.
