I am studying the paper of Dimca and Papadima Hypersurface complements, Milnor fibers and higer homotopy groups of arrangements and try do use the their techniques in order to study some topological properties of the complement manifold of toric arrangements.

However, I have some basic questions in complex algebraic geometry. In particular, I would like to better understand the relationship between the complement manifold of a hypersurface in the projective space and the complement manifold of its affine part. To be more specific, here is my question.

**Question**
Let $F\in\mathbb{C}[x_{0},\ldots,x_{n}]$ be a homogeneous polynomial and let $M(F)$ be the complement manifold of the hypersurface $\{F=0\}$ in the complex projective space $\mathbb{CP}^{n}$. Let $M(F)_{a}$ be the complement manifold in $\mathbb{C}^{n}$ of the affine part of $F$. How the topology of $M(F)$ and $M(F)_{a}$ are related?
