Switched signed graphs of integer additive set-valued signed graphs

Discrete Mathematics, Algorithms and Applications, 2017
Let [Formula: see text] denote a set of non-negative integers and [Formula: see text] be its power set. An integer additive set-labeling (IASL) of a graph [Formula: see text] is an injective set-valued function [Formula: see text] such that the induced function [Formula: see text] is defined by [Formula: see text], where [Formula: see text] is the ...

On graphs with signed inverses

Networks, 1988
AbstractA graph G is called invertible if its adjacency matrix A has an inverse which is the adjacency matrix of some graph H. All such graphs were shown by Harary and Minc to have the form nK2. We now introduce signed invertible (or briefly s‐invertible) graphs G as those whose inverse H is a signed graph.

Domination in signed graphs

Discrete Mathematics, Algorithms and Applications, 2020
Let [Formula: see text] be a graph. A signed graph is an ordered pair [Formula: see text] where [Formula: see text] is a graph called the underlying graph of [Formula: see text] and [Formula: see text] is a function called a signature or signing function. Motivated by the innovative paper of B. D.

Signs, Symbols and Graphs

1987
This chapter looks at all the forms of diagrams which give information; these include (a) signs and symbols used to instruct, advise or warn; (b) graphs and charts; (c) diagrams used to represent planned sequences (flowcharts); (d) three-dimensional representation.
