Minimal Sum Labeling of Graphs [PDF]

open access: yesJournal of Discrete Algorithms, 2018
A graph $G$ is called a sum graph if there is a so-called sum labeling of $G$, i.e. an injective function $\ell: V(G) \rightarrow \mathbb{N}$ such that for every $u,v\in V(G)$ it holds that $uv\in E(G)$ if and only if there exists a vertex $w\in V(G)$ such that $\ell(u)+\ell(v) = \ell(w)$. We say that sum labeling $\ell$ is minimal if there is a vertex

On Square Sum Labeling of Two Families of Petersen Graphs

open access: yesJournal of Mathematics, 2022
A labeling on a graph G with n vertices and m edges is called square sum if there exists a bijection f:VG⟶0,1,2,3,…,n−1 such that the function f∗:EG⟶N defined by f∗st=fs2+ft2, for all st∈EG, is injective.

On Integer Cordial Labeling of Some Families of Graphs

open access: yesRatio Mathematica, 2022
An integer cordial labeling of a graph $G(p,q)$ is an injective map $f:V\rightarrow [-\frac{p}{2}...\frac{p}{2}]^*$ or $[-\lfloor{\frac{p}{2}\rfloor}...\lfloor{\frac{p}{2}\rfloor}]$ as $p$ is even or odd, which induces an edge labeling $f^*: E ...

Enumeration Of Labelled Graphs [PDF]

open access: yesCanadian Journal of Mathematics, 1956
1. Introduction. The number of connected linear graphs having V vertices labelled 1, … , V and λ (unlabelled) lines is found below. Similar formulas are found for graphs in which slings, lines “in parallel,” or both are allowed and for directed graphs with or without slings or parallel lines.

Antimagic labeling of regular graphs [PDF]

open access: yes, 2016
A graph G = (V, E ) is antimagic if there is a one-to-one correspondence f : E → {1, 2,..., |E|} such that for any two vertices u, v, Σe∈ E(u) f(e)≠Σe∈E(v ) f(e).

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
