| Outline of Final Research Achievements |
We have newly introduced the subdivided-line graph operation and defined the class of iterated subdivided-line graphs which essentially contains well-known graph classes with self-similar structures such as the Sierpinski graphs and the extended Sierpinski graphs. We have then studied their structural properties such as edge-disjoint Hamilton cycles, hamiltonian-connectivity, hub sets, connected dominating sets, independent spanning trees, completely independent spanning trees, various colorings and labelings, globally h-connected defensive t-alliances, and (h,l)-connected dominating sets. We have also shown results on structural properties for base graphs of injective graph expansions. Moreover, we have newly introduced the class of universalized Sierpinski graphs which contains both the classes of generalized Sierpinski graphs and extended Sierpinski graphs, and then studied their structural properties which can be applied to fault-tolerant problems on interconnection networks.
