Map Color Theorem

The narrative explores the journey of proving the Heawood Conjecture, initially proposed in 1890 and later validated in 1968, transforming it back into the Map Color Theorem. The book highlights the collaborative efforts between mathematicians J. W. T. Youngs and the author, detailing their work on the remaining unsolved cases. It emphasizes the joy and intellectual satisfaction derived from their partnership, alongside the development of elegant combinatorial methods. Personal correspondence adds a historical touch, illustrating their shared enthusiasm for mathematical discovery.
