| Jan 15, 2016 at 14:54 | comment | added | Fedor Petrov | Does not Schoenberg's theorem work in $\mathbb{R}^n$? | |
| Jan 15, 2016 at 14:54 | comment | added | Dirk | I guess $|x|$ is the euclidean norm in n dimensions... | |
| Jan 15, 2016 at 14:47 | comment | added | Suvrit | @Dirk: I answered the question written in the title...I did not look at the main text :-) | |
| Jan 15, 2016 at 14:44 | comment | added | Dirk | Not sure if you answered the right question. Note that dimension of the domain is also $n$. | |
