Riemannian geometry and Symmetries, Hyperbolic Spaces

46 Views Asked by At

I am currently trying to connect Hyperbolic geometry through several models with Riemannian geometry. At first I have transformed the metric tensor from sphere in $R^3$ and the pseudo-sphere in $R^{2,1}$ through stereographic projection, complex transformations etc. After that I am trying to transform the induced symmetries(independent Killing vectors) of $R^3$ and $R^{2,1}$ on the sphere and pseudo-sphere in all these several coordinate system. This process is supposed to reveal the Riemannian structure of hyperbolic spaces. I need some help to make the connection. Thank you
