Abstract:
We consider unitary representations of finite groups acting on $\mathbb{R}^n$. Such a representation induces a natural metric over the space of orbits, that we call homogeneous metric space. This paper presents a universal construction of bi-Lipschitz Euclidean embeddings of such homogeneous metric spaces which are intrinsically group invariant.
