Are the spaces $T_pM$ and $\mathbb R^n$ homeomorphic?

187 Views Asked by At

Let $T_pM$ be the tangent space at a point $p$ in a n-dimensional smooth manifold $M$.

In addition, if we assume $(M,g)$ as a smooth Riemannian manifold, then $T_pM$ is a n-dimensional real normed-linear space (real NLS).

Since, every finite-dimensional NLS (over same field) with same dimension are isomorphic, $T_pM$ and $\mathbb R^n$ are isomorphic.

My question is : Are the spaces $T_pM$ and $\mathbb R^n$ homeomorphic?

We know that in a finite dimensional linear space any two norms are equivalent i.e. induced topologies are same.

But, if two NLS are isomorphic, are the topological spaces induced by the norms homeomorphic?

Thanks a lot in advance. Any help will be appreciated.
