Abstract

This study explores the On decomposition of the complement of a graph derived from two star graphs, denoted as . In this context, K₁,ₘ and K₁,ₙ are star graphs with one central vertex and m and n peripheral vertices, respectively. The ":" operator symbolises a specific binary graph operation, such as a graph join, that integrates these two star graphs into a single structure. This research focuses on the complement of the resulting graph, wherein edges exist between previously non-adjacent vertex pairs. The primary objective is to examine how this complemented graph can be decomposed into subgraphs that meet the on decomposition criteria. The On decomposition refers to a partitioning method in which the graph is divided into components satisfying specific neighbourhood or structural constraints, often relevant in graph optimisation and algorithm design. Results of this study provide new insights into the structure and decomposition of complex graphs, with potential implications for theoretical computer science, network analysis, and data structures.
