Abstract
A (p,q) graph G is said to admit centered triangular sum labeling if its vertices can be labeled by non negative integers such that the induced edge labels obtained by the sum of the labels of end vertices are the first q centered triangular numbers. A graph G which admits centered triangular sum labeling is called centered triangular sum graph. In this paper we prove that paths, combs, stars, subdivision of stars, bistars and coconut trees and admit centered triangular sum labeling.
