(Reflexive Edge Strenght on Triangular Chain Graph)
Abstract
Given a simple connected graph î€ with set of vertices is î€ and set of edge is î€. A graph î€ is called to have an edge irregular reflexive î€-labeling if each vertices can be labeled with an even positive integer î€ and each edge can be labeled with a positive integer î€ such that each edge has a different weight. The weight of an edge î€ on a graph î€ is the sum of the vertex label î€, vertex label î€, and î€ edge label. The reflexive edge strenght of a graph î€ denoted by î€ is the minimum î€ of the largest label in graph î€ with î€. In this paper, we determine the reflexive edge strenght of the triangular chain graph î€-path for î€. The reflexive edge strenght of the triangular chain graph î€-path is 3 for î€, î€ for î€ is even and î€, and î€ for î€ is odd.
