Cyclically Interval Total Coloring of the One Point Union of Cycles
2018
A total coloring of a graph G with colors 1, 2, ..., t is called a
cyclically interval total t-coloring if all colors are used, and the edges incident to each vertex v∈V(G) together with v are colored by (dG(v)+1) consecutive
colors modulo t, where dG(v) is the degree
of the vertex v in G. The one point union of k-copies of cycle Cn is the graph
obtained by taking v as a common vertex such that any two distinct cycles C'n and C"n are edge disjoint
and do not have any vertex in common except v. In this paper, we study the cyclically interval total colorings of , where n≥3 and k≥2.
