چکیده
|
A graph g with q edges is said to be harmonious,if there is an injection f from the vertices of g to the group of integers modulo q such that when each edge xy is assigned the label f(x)+f(y) (mod q),the resulting edge labels are distinct. in this paper,we study the existence of harmonious labeling for the corona graphs of a cycle and a graph g and for the corona graph of k2 and a tree. © 2014 martin bača and maged z. youssef.
