Let $X$ be a (singular) projective variety, in other words something given by a collection of polynomial equations in $\mathbb CP^n$ or $\mathbb RP^n$. How one proves that it is a finite $CW$ complex?
Similar question. Suppose that $X$ affine (i.e. given by polynomial equations in $\mathbb C^n$, or $\mathbb R^n$). How one proves that its one point compactification is a finite $CW$ complex?
These questions are sequel to the discussions here:
