Deep Graph Theory delves into the philosophical implications of classical graph theory statements, questioning concepts like trees and forests. It challenges traditional definitions, such as considering a single tree as a forest. Future work includes converting caterpillar graphs to butterfly graphs and using graphs to predict success in football coaching.

DEEP GRAPH THEORY
What is Deep Graph Theory? • Takes graph theory statements out of context, and examines their philosophical implications.
Example: Trees and Forests • Forest: an undirected, acyclic graph. • Tree: an undirected, acyclic, connected graph.
Example: Trees and Forests • Forest: an undirected, acyclic graph. • Tree: an undirected, acyclic, connected graph.
Every tree is a forest!
Example: Trees and Forests • Forest: an undirected, acyclic graph. • Tree: an undirected, acyclic, connected graph. • We usually think of forests as a bunch of trees • That’s wrong! A single tree, on its own, is a forest.
Future work • Converting caterpillar graphs into butterfly graphs. • Using the Petersen graph to predict Coach Petersen’s success leading Washington football. • Think of more graph theory jokes non-theorists can understand.
