| Abstract: | (Lower integral) sum labeling and exclusive (lower integral) sum labeling are ways used as compressed representation of a graph. A graph G is said to be an lower integral sum graph if it is isomorphic to the lower integral sum graph of some SQ+. A graph Pn×K2 is called ladder. This paper gives a definition of the subdivision graph of ladder, and has proved the exclusive (lower) integral sum number of the subdivision graph of ladder. |
