Abstract

Let G be a simple connected graph with order n(G), local metric dimension \rm diml(G), local adjacency metric dimension \rm dimA,l(G), and clique number ω(G), where G\not≅ Kn(G) and ω(G)≥3. It is proved that \rm dimA,l(G) ≤ \lfloor ((ω(G) - 2)/(ω(G) - 1))n(G)\rfloor. Consequently, the conjecture asserting that the latter expression is an upper bound for \rm diml(G) is confirmed. It is important to note that there are infinitely many graphs that satisfy the equalities.
