on k-prime labeling
Dr. Maged Zakaria
Abstract
A simple graph of order n is said to have a prime labeling if its vertices can be bijectively labeled with the integers 1, 2,..., n such that the adjacent vertices have relatively prime labels. The graph which admits prime labeling is called a prime graph. In 2011, Vaidya introduced a little variation on prime labeling. He calls a simple graph of order n have a k-prime labeling if its vertices can be bijectively labeled with the integers k,k+1,...,k+n-1, where k is a positive integer, such that the adjacent vertices have relatively prime labels. In this talk, we arise some open problems about k-prime labeling.
A simple graph of order n is said to have a prime labeling if its vertices can be bijectively labeled with the integers 1,2,...,n such that adjacent vertices have relatively prime labels. The graph which admits prime labeling is called a primegraph. In this talk we give some necessary conditions for graphs to be prime.
