GRAPH THEORY: Research Directions, contains ten articles, mainly survey type, on some current research areas in Graph Theory, namely, graceful labeling, L(2,1)-labelling, complexity of graph labeling problems, dominations, interval graphs, matrices and graphs, colouring of labelled graphs and hypergraphs, self-complementary graphs, and strongly regular graphs. Several research problems have been mentioned in the book and at the end of each article a number of references have been included. This book will be beneficial for researchers and useful for beginners who want to do research in these topics.
