Abstract

In this paper we introduce relatively prime geodetic number of a graph G. Let G be a connected graph. A set SV is said to be a relatively prime geodetic set if it is a geodetic set with at least three elements and the shortest distance between any two pairs of vertices in S is relatively prime. The relatively prime geodetic set of G is denoted by grp(G)-set. The cardinality of a minimum relatively prime geodetic set is the relatively prime geodetic number and it is denoted grp(G).

Keywords:

Geodetic set, Geodetic Number, Relatively prime, Line graph
