Sum Divisor Cordial Labeling of Wheel Related Graph FamiliesBy Divya G. Adalja
Abstract: In this paper, we prove that the graphs obtained by switching of a rim in wheel Wn, switching of a vertex of degree 2 and 3 in gear graph Gn, switching of a vertex of degree 2 and 4 in flower graph fln, switching of a vertex of degree 2 and 3 in shell graph Sn are sum divisor cordial (SDC). A sum divisor cordial labeling (SDCL) of a graph …
