Brooks' Theorem

MICHAEL STIEBITZ graduated from Humboldt University in Berlin in 1977. He obtained a doctorate at the Technical University of Ilmenau in 1981 and has served as professor there until 2022. He has published around 70 research papers on graph theory, in particular on coloring problems. He is the main author of the book Graph Edge Coloring (Wiley 2012). THOMAS SCHWESER obtained a doctorate at the Technical University of Ilmenau in 2020, supervised by Michael Stiebitz. He has published around 15 research papers and is currently working in the private industrial sector as a researcher in database theory. BJARNE TOFT graduated from Aarhus University in 1968 and obtained a doctorate from the University of London in 1970. He is author of around 65 research papers. His mathematical interests are graph theory, combinatorial game theory and the history of mathematics. He co-authored Graph Coloring Problems (Wiley 1995), and is second author of Graph Edge Coloring (Wiley 2012) and HEX The Full Story (CRC Press 2019)

“There are multiple problems in each chapter, copious notes on the results and a substantial bibliography. It seems likely this book will be a valuable resource for results and methods in this area for a long time.” (David B. Penman, zbMATH 1536.05004, 2024)
