A Study on Topological Integer Additive Set-Labeling of Graphs [PDF]
Electronic Journal of Graph Theory and Applications, 2015 A set-labeling of a graph $G$ is an injective function $f:V(G)\to \mathcal{P}(X)$, where $X$ is a finite set and a set-indexer of $G$ is a set-labeling such that the induced function $f^{\oplus}:E(G)\to \mathcal{P}(X)-\{\emptyset\}$ defined by $f ...

A study on integer additive set-valuations of signed graphs [PDF]
Karpatsʹkì Matematičnì Publìkacìï, 2015 Let $\mathbb{N}_0$ denote the set of all non-negative integers and $\mathcal{P}(\mathbb{N}_0)$ be its power set. An integer additive set-labeling (IASL) of a graph $G$ is an injective set-valued function $f:V(G)\to\mathcal{P}(\mathbb{N}_0)\setminus ...

Topological Integer Additive Set-Sequential Graphs
Mathematics, 2015 Let \(\mathbb{N}_0\) denote the set of all non-negative integers and \(X\) be any non-empty subset of \(\mathbb{N}_0\). Denote the power set of \(X\) by \(\mathcal{P}(X)\). An integer additive set-labeling (IASL) of a graph \(G\) is an injective function

(s, d) Magic Labeling of some ladder graphs [PDF]
E3S Web of Conferences, 2023 Let G(p, q) be a connected, undirected, simple and non-trivial graph with q nodes and q lines. Let f be an injective function f: V(G) →{ s, s + d, s + 2d,.....s + (q +1)d } and g be an injective function g: E(G) → {d,2d,3d,… 2(q-1)d}.Then the graph G is ...

Injectiveness and Discontinuity of Multiplicative Convex Functions
Mathematics, 2021 In the present work we study the set of multiplicative convex functions. In particular, we focus on the properties of injectiveness and discontinuity. We will show that a non constant multiplicative convex function is at most 2-injective, and construct ...

On analytic injective matrix functions [PDF]
Proceedings of the American Mathematical Society, 1983 An ingenious generalization of univalent functions of one complex variable into matrix functions was introduced by B. Schwarz, along with two conjectures corresponding to the first coefficient problem and the second coefficient problem for the traditional classes Σ \Sigma and S S , respectively.

On i-Continuous Functions [PDF]
مجلة التربية والعلم, 2019 In this paper we prove that the function is i-open if it is injective, surjective and i-continuous from i-compact topological space into -space. Further, we define and find the relationship among some i-separation axioms such as, and.
