Exact Rainbow Numbers for Cycle-Related Graphs in Multi-Hubbed Wheels
Analysis
This paper determines the exact rainbow number for specific graph structures (multi-hubbed wheels and chorded cycles) which is important for applications in areas like wireless communication and network analysis. It solves problems proposed by previous researchers and generalizes existing results, providing a complete solution for rainbow numbers of cycles in large wheel graphs.
