摘要

Zariski van-Kampen Theorem is a tool for computing fundamental groups of complements to curves (germs of curve singularities, affine plane curves and projective plan curves). It gives you the fundamental groups in terms of generators.

It will be divided into several talks. In the first talk, I will talk about the preliminary of the fundamental group, presentation of groups. In addition, I will give the computations of the fundamental groups of some examples by the Van Kampen theorem.
