Forbidden Subgraph Earrings $49

These earrings show two special mathematical objects --- the complete graph on five vertices (K_5) and the complete bipartite graph with six vertices (K_{3,3}). Together they give complete information about when a graph can be drawn on paper without crossings. This is known as Kuratowski's Theorem.

The aspiring Graph Theorist will also be interested in the matching Petersen Graph Pendant from the same collection.
