Star coloring for a special class of graphs G1,d

In this paper we study the star coloring for a special class of graphs whose degree is either 1 or d. They are graphs obtained by generalized corona products of path, circle, star, complete graph complete bipartite graph and complement of complete graph respectively. Vertex coloring theory of graphs is an important part of graph coloring theory. Star coloring is a special vertex coloring with limited conditions..
