These notes are based on the part IIA mathematics course ``Graph theory'' given by Dr Fisher in Cambridge in Michaelmas 2003. These notes are not connected to Dr Fisher in any way. Dr Fisher was an exceptionally careful lecturer had a much better set of notes, which was (as far as I know) perfect.
However, there are numerous horrible, basic mistakes in my notes. For example, graph colouring was spelt graph colourling and fundamental definitions are often utterly wrong. Please don't rely on these notes. However, feel free to send corrections to me.
