Abstract
A signed dominating function of graph Γ is a function such that
for each
The signed domination number
is the minimum weight of a signed dominating function on Γ. Let
be a finite group such that
In this paper, we obtain the signed domination number of
based on cardinality of S. Also we determine the classification of group G by
and
