Abstract
Let Möb(\(\mathbb{S}^{{n + 1}}\)) denote the Möbius transformation group of \(\mathbb{S}^{{n + 1}}\). A hypersurface f: \({M^n} \to \mathbb{S}^{{n + 1}}\) is called a Möbius homogeneous hypersurface, if there exists a subgroup \(G \triangleleft {\text{M}}\ddot o{\text{b}}{(^{n + 1}})\) such that the orbit G(p) = {ϕ(p) ∣ ϕ ∈ G} = f (Mn),p ∈ f (Mn). In this paper, we classify the Möbius homogeneous hypersurfaces in \(\mathbb{S}^{{n + 1}}\) with at most one simple principal curvature up to a Möbius transformation.
