On Non-Zero Vertex Signed Domination

Symmetry, 2023
For a graph G=(V,E) and a function f:V→{−1,+1}, if S⊆V then we write f(S)=∑v∈Sf(v). A function f is said to be a non-zero vertex signed dominating function (for short, NVSDF) of G

Edges and Vertices in a Unique Signed Circle in a Signed Graph

AKCE International Journal of Graphs and Combinatorics, 2017
We examine the conditions under which a signed graph contains an edge or a vertex that is contained in a unique negative circle or a unique positive circle.
