Feynman Diagrams and Map Enumeration
The goal of this thesis is to count how many graphs exist given a number of verticesor some other restrictions. The graphs are counted by perturbing Gaussian integralsand using the Wick lemma to interpret the perturbations in terms of graphs. Fatgraphs, a specific type of graph, are central in this...
