On The Local Metric Dimension of Line Graph of Special Graph
Let G be a simple, nontrivial, and connected graph. is a representation of an ordered set of <em>k</em> distinct vertices in a nontrivial connected graph G. The metric code of a vertex <em>v</em>, where <em>, </em>the ordered of <em>k</em>-vector is representations of <em>v</em> with respect to <em>W</em>, where is the distance between the vertices <em>v</em> and <em>w<sub>i</sub></em> for 1≤ <em>i ≤k</em>. Furthermore, the set W is called a local resolving set of G if for every pair <em>u</em>,<em>v </em>of adjacent vertices of G. The local metric dimension ldim(G) is minimum cardinality of <em>W</em>. The local metric dimension exists for every nontrivial connected graph G. In this paper, we study the local metric dimension of line graph of special graphs , namely path, cycle, generalized star, and wheel. The line graph L(G) of a graph G has a vertex for each edge of G, and two vertices in L(G) are adjacent if and only if the corresponding edges in G have a vertex in common.
