A Study on Set-Valuations of Signed Graphs

P. K. Ashraf, K. A. Germina, N. K. Sudev

Let $X$ be a non-empty ground set and $P (X)$ be its power set. A set-labeling (or a set-valuation) of a graph $G$ is an injective set-valued function $f:V(G)\to \mathcal{…

Some New Results on Integer Additive Set-Valued Signed Graphs

N. K. Sudev, P. K. Ashraf, K. A. Germina

Let $X$ denotes a set of non-negative integers and $P (X)$ be its power set. An integer additive set-labeling (IASL) of a graph $G$ is an injective set-valued function $f:…
