Difference Cordial Labeling of 2-tuple Graphs of Some Graphs
P L Vihol, P. H. Shah · International Journal of Mathematics And its Applications · 2016
In this paper, we introduce new notion called 2-tuple graph of an undirected simple graph and we investigate the difference cordiality of 2-tuple graphs of Crown $Cr_n$, Wheel $W_n$, Ladder graph ${P_n} \times {P_2}$, Triangular snake $T_{n}$, Quadrilateral snake $Q_{n}$,Middle graph of path $P_{n}$ and cycle $C_n$ etc.
