The d(G = Cm ×Kn, χ(G))
has been studied. In this note we
show that the exact value of defining number d(G = Cm×Kn,c) with
c > χ(G), where n ≥
2 and m ≥ 3, unless the defining number
d(K3×C2r,4), which is given an upper and lower bounds for this
defining number. Also some bounds of defining number are introduced.
Keywords: graph coloring, defining set, cartesian product.
