Abstract
Let x: M n → Sn+1 be an immersed hypersurface in the (n + 1)-dimensional sphere Sn+1. If, for any points p, q ∈ M n, there exists a Möbius transformation ϕ: Sn+1 → Sn+1 such that ϕ ○ x(M n) = x(M n) and ϕ ○ x(p) = x(q), then the hypersurface is called a Möbius homogeneous hypersurface. In this paper, the Möbius homogeneous hypersurfaces with three distinct principal curvatures are classified completely up to a Möbius transformation.
