| May 17, 2023 at 13:25 | comment | added | user45397 | Thanks. I had two questions. 1) I understand that $T_pV$ is $4$-dimensional. How are there "$4$ parameters for a 2-dimensional subspace in the tangent space"? 2) Why do we not consider the case of 3-dimensional subspace in the tangent space? | |
