Consider the affine hyperquadric $Q:=\biggl\{(z_1,...,z_{n+1})\in\mathbb{C}^{n+1}\biggl|\sum_{i=1}^{n+1}z_i^2=1\biggr\}\cong TS^n$.

>What is a reasonable Kähler metric for $Q$?
Furthermore, what is the curvature form $\Omega$ on $Q$? Hence, compute the Chern classes of $Q$. Given this, how do we compute $\chi(Q,\mathcal{O}_Q)$?
