Abstract:
Let $n\ge 2$ be an integer and let $\mathcal {D}$ be a domain of $\mathbb {R}^n$. Let $f:\mathcal {D}\to \mathbb {R}^n$ be an injective mapping which takes hyperspheres whose interior is contained in $\mathcal {D}$ to hyperspheres in $\mathbb {R}^n$. Then $f$ is the restriction of a Möbius transformation.References
