Presentation Time

I'm back in the department. I feel ill and unmotivated and I have to write a presentation. I have no idea what I am actually going to write about. There are currently 3 options,

1. The Combinatorics of the (multiple) polylogarithm.
2. Introduction to Hodge Structures/ Mixed Hodge Structures.
3. Single valued functions for the (multiple) polylogarithms from the Variations of Mixed Hodge Structures of the (multiple) polylogarithms.

As much as I would like to do one of my last 2 options, I really can't. I have to think of my audience. So it looks like option 1 it is....
