Integral Root Labeling of Graphs


V.L. Stella Arputha Mary, N. Nanthini
Abstract

Let ๐บ = ๐‘‰,๐ธ be a graph with ๐‘ vertices and ๐‘ž edges. Let ๐‘“: ๐‘‰ โ†’ 1,2, โ€ฆ ๐‘ž + 1 is called an Integral Root labeling if it is possible to label all the vertices ๐‘ฃ โˆˆ ๐‘‰ with distinct elements from 1,2, โ€ฆ ๐‘ž + 1 such that it induces an edge labeling ๐‘“ +: ๐ธ โ†’ 1,2, โ€ฆ ๐‘ž defined as ๐‘“ +(๐‘ข๐‘ฃ) = (๐‘“ ๐‘ข ) 2+(๐‘“ ๐‘ฃ ) 2+๐‘“ ๐‘ข ๐‘“(๐‘ฃ) 3 is distinct for all ๐‘ข๐‘ฃ โˆˆ ๐ธ. (i.e.) The distinct vertex labeling induces a distinct edge labeling on the graph. The graph which admits Integral Root labeling is called an Integral Root Graph. In this paper, we introduce Integral Root labeling and investigate Integral Root labeling of Path, Comb, Ladder, Triangular Snake and Quadrilateral Snake.

Keywords
Integral Root labeling, Integral Root graph, Path, Comb, Ladder, Triangular Snake, and Quadrilateral Snake.
