An ordered subset of nodes of is called a resolving set or locating
set for if each node is individually determined by its code of distances to the nodes in . A
resolving set of minimum number of nodes is called a basis for and this cardinality is the
metric dimension or location number of , represented as
In this thesis, we compute the metric dimension of some wheel related graphs, such as m-level
gear graph, m-level antiweb-wheel graph, m-level antiweb-gear graph and an infinite class of
convex polytopes denoted by
, respectively. We prove that the
metric dimension of aforementioned wheel related graphs and a family of convex polytope is not
bounded. The unbounded metric dimension of convex polytope also furnish a negative answer to
the problem given in [19]:
Open Problem: “Is it the case that the graph of every convex polytope has constant metric
dimension?”
It is natural to ask for characterization of graphs with unbounded metric dimension. |
