Packing Chromatic Number of Bismuth Tri-iodide and First Type Nanostar Dendrimers

Abstract

The packing chromatic number ( ) Gof a connected graphGis the smallest numbermforwhich a functiong V G m : ( ) {1,2,..., } exists, such that ifg a g b j ( ) ( ) ,  thend a b j ( , )  .Here, we determine the packing chromatic numbers of bismuth tri-iodide and first type nanostardendrimers.
