# Higher-Dimensional Metrics in (Hyper)-Spherical Coordinates

I want to compute the components of the Riemann curvature tensor (for a case similar to the Schwarzschild solution) in 4 + 1 dimensions, but I want to use a higher-dimensional analogue of spherical coordinates. I first want to investigate a metric for the Euclidean case, i.e. "flat" space-time with no matter or energy present. How would I write this Euclidean metric using a higher-dimensional analogue of spherical coordinates?

• This link might help: en.wikipedia.org/wiki/N-sphere#Spherical_coordinates – G. Paily Jul 29 '14 at 19:01
• Thanks. I had already found that page, but I've been looking for a confirmation of it. en.wikipedia.org/wiki/… also has some information, but, again, I've been looking for a non-Wikipedia source. – HDE 226868 Jul 29 '14 at 19:04
• So, this?: mathworld.wolfram.com/Hypersphere.html :-D . If you look around equation 12 he gives essentially the same coordinates as the wiki article, he just numbers them differently. Confirmation is given by equation 16. Then you just need to construct $dx^{1}$, $dx^{2}$, etc. – G. Paily Jul 29 '14 at 19:10
• Thanks again. This is exactly what I need. The initial discussion is also helpful. – HDE 226868 Jul 29 '14 at 19:19
• Hi HDE 226868. If you haven't already done so, please take a minute to read the definition of when to use the homework-and-exercises tag, and the Phys.SE policy for homework-like problems. – Qmechanic Mar 19 '15 at 9:42
