WebMay 18, 2024 · Tutte’s research in the field of graph theory proved to be of remarkable importance. At a time when graph theory was still a primitive subject, Tutte commenced the study of matroids and developed them into a theory by expanding from the work that Hassler Whitney had first developed around the mid 1930s. WebFeb 16, 2024 · This book provides a systematic treatment of the theory of graphs without sacrificing its intuitive and aesthetic appeal, and is suitable as a textbook for advanced undergraduate and beginning graduate students in mathematics and computer science.

WebJan 27, 2024 · The proof would be constructive if it helped in finding a 1-factor given that Tutte's condition holds, but it does not. The proof builds an edge-maximal graph G' containing G that does not contain a 1-factor, and finds a set S that violates Tutte's condition in G'. Building such a G' would require a decision procedure that answers …
