Abstract

Radial Signed Digraphs

P. Siva Kota Reddy, P. S. Hemavathi and R. Rajendra

In this paper, we define the radial signed digraph −→R(Σ) of a given signed digraph Σ = (∆, σ) and offer a structural characterization of radial signed digraphs. Further, we characterize signed digraphs Σ for which: Σ ∼ −→R(Σ) and Σ ∼ −→R(Σ) where ∼ denotes switching equivalence and −→R(Σ) and Σ are denotes the radial signed digraph and complementary signed digraph of Σ respectively.
