A sharp upper bound for the number of stable sets in graphs with given number of cut edges
Let G be a connected and simple graph, and let i ( G ) denote the number of stable sets in G . In this letter, we have presented a sharp upper bound for the i ( G ) -value among the set of graphs with k cut edges for all possible values of k , and characterized the corresponding extremal graphs as w...

Summary: | Let
G
be a connected and simple graph, and let
i
(
G
)
denote the number of stable sets in
G
. In this letter, we have presented a sharp upper bound for the
i
(
G
)
-value among the set of graphs with
k
cut edges for all possible values of
k
, and characterized the corresponding extremal graphs as well. |
