Tutte's characterizations of graphic and regular matroids

In a series of three papers, Tutte proved excluded-minor characterizations for graphic and regular matroids. I found the classification of graphic matroids a particularly beautiful result since it generalizes Kuratowski's excluded-minor criterion for planar graphs.

We give an overview of the theory in general, and look into some of the terminology and techniques developed by Tutte as stepping-stones to his two main theorems.
