Abstract
A two-valued function f defined on the vertices of a graph G=(V, E), ?: ? ? {?1, 1} is a signed dominating function (SDF) if the sum of its function values over any closed neighborhood is at least one. The weight of a signed dominating function is defined to be (?) = ? ?(?), over all vertices ? ? ?. The signed dominating number of a graph G, denoted by ??(?) ??? ??(?) = min{w(?)}, where f is signed dominating function of G. In this paper, characterize the class of graphs for signed domination number one with respective to induced subgraphs.
