''Alexander polynomial of complex algebraic curve''
 
I will extend the definition of Alexander polynomial in knot theory to an complex algebraic curve.
From the definition, it is clear that Alexander polynomial is an topological invariant for curves.
I will explain how the topology of a curve control its Alexander polynomial, in terms of the factors.
Calculations of some examples will be provided.
