The problems arising from the study of a variety of labelling schemes of the elements of any discrete structure such as a graph, a directed graph, a hypergraph or a signed graph is a potential area of research with a lots of challenging unsolved problems.

Research papers giving recent developments and directions for further research on topics such as graceful labelings, graph decomposition, multiplicative labelings, set labelings, sigma graphs, orthogonal labelings, Skolem and Hooked Skolem graceful labelings for graphs and signed graphs, set magic labeling, k-equitable graphs and Arithmetic graphs by leading experts in the respective fields are included in this volume.

This volume will serve as an excellent reference for experts and research scholars working on Graph Labeling Problems.
