“The writing is crisp, clear and instructive, appropriate for undergraduates with a grasp of graph theory fundamentals. … The book is best suited as a companion text to introduce undergraduate students to graph labeling problems, perhaps via a research workshop.” (André E. Kézdy, Mathematical Reviews, April, 2020)
This book depicts graph labelings that have led to thought-provoking problems and conjectures. Problems and conjectures in graceful labelings, harmonious labelings, prime labelings, additive labelings, and zonal labelings are introduced with fundamentals, examples, and illustrations. A new labeling with a connection to the four color theorem is described to aid mathematicians to initiate new methods and techniques to study classical coloring problems from a new perspective. Researchers and graduate students interested in graph labelings will find the concepts and problems featured in this book valuable for finding new areas of research.
