Linear Algebra and the Hanna Neumann Conjecture
- Postscript version.
- Dvi version.
- PDF version.
In this paper we give a short proof of the Hanna Neumann Conjecture (HNC)
only basic linear algebra, group theory, and algebraic geometry.
We also give a number of exercises, partly to develop simpler material,
and partly to give the reader more intuition for our new point of view.
This article is currently a work in progress;
we plan to keep adding more material, discussing more mathematics
related to the HNC.
All material is presented ``from scratch,'' assuming only a basic knowledge
of linear algebra and group theory.
