| ''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.
