This study explores the On decomposition of the complement of a graph
derived from two star graphs, denoted as <K₁,ₘ : K₁,ₙ>. 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.
