Symmetry in a $p$-sphere

34 Views Asked by At

Let $S(p)$ be the unit sphere at the origin in the $\mathcal{l}_p$-norm. What symmetries does it have? For instance in the $\mathcal{l}_2$-norm we have unitary symmetry in the Euclidean case. In general for $\mathcal{l}_p$-norm what can we expect for Euclidean, Elliptic and Hyperbolic spaces?
