To understand how a complex variety sits in affine or projective space, one can study topological invariants of its complement. These complements sometimes also parametrize the 'nice' objects of a moduli space. I will discuss the Zariski–van Kampen method to compute the fundamental group of the complement of an algebraic curve in the plane, and explicitly compute some examples.
