On randomly k -dimensional graphs
For an ordered set W = { w 1 , w 2 , … , w k } of vertices and a vertex v in a connected graph G , the ordered k -vector r ( v | W ) : = ( d ( v , w 1 ) , d ( v , w 2 ) , … , d ( v , w k ) ) is called the (metric) representation of v with respect to W , where d ( x , y ) is the distance between the...

Summary: | For an ordered set
W
=
{
w
1
,
w
2
,
…
,
w
k
}
of vertices and a vertex
v
in a connected graph
G
, the ordered
k
-vector
r
(
v
|
W
)
:
=
(
d
(
v
,
w
1
)
,
d
(
v
,
w
2
)
,
…
,
d
(
v
,
w
k
)
)
is called the (metric) representation of
v
with respect to
W
, where
d
(
x
,
y
)
is the distance between the vertices
x
and
y
. The set
W
is called a resolving set for
G
if distinct vertices of
G
have distinct representations with respect to
W
. A resolving set for
G
with minimum cardinality is called a basis of
G
and its cardinality is the metric dimension of
G
. A connected graph
G
is called a randomly
k
-dimensional graph if each
k
-set of vertices of
G
is a basis of
G
. In this work, we study randomly
k
-dimensional graphs and provide some properties of these graphs. |
