Volume 50, Issue 1 , June 2018, Pages 1-28

https://doi.org/10.22059/jac.2018.7989

Abstract
  In $1994,$ degree distance  of a graph was introduced by Dobrynin, Kochetova and Gutman. And Gutman proposed the Gutman index of a graph in $1994.$ In this paper, we introduce the concepts of  multiplicative version of degree distance and the multiplicative version of Gutman index of a graph. ...  Read More

Volume 50, Issue 1 , June 2018, Pages 101-108

https://doi.org/10.22059/jac.2018.68342

Abstract
  A graph $G$ is said to be one modulo three geometric mean graph if there is an injective function $\phi$ from the vertex set of $G$ to the set $\{a \mid 1\leq a \leq 3q-2\} $ and either $a\equiv 0(mod 3) $ or $ a\equiv 1(mod 3)\}$ where $q$ is the number of edges of $G$ and $\phi$ induces a bijection ...  Read More

Volume 50, Issue 1 , June 2018, Pages 109-118

https://doi.org/10.22059/jac.2018.68367

Abstract
  The analysis of vulnerability in networks generally involves some questionsabout how the underlying graph is connected. One is naturally interestedin studying the types of disruption in the network that maybe causedby failures of certain links or nodes. In terms of a graph, the concept ofconnectedness ...  Read More

Pointed Conflict-Free Colouring of Digraphs

Mahdieh Hasheminezhad

Volume 50, Issue 1 , June 2018, Pages 119-131

https://doi.org/10.22059/jac.2018.68425

Abstract
  In a pointed conflict-free partial   (PCFP) colouring of a digraph, each vertex has at least  one in-neighbour with unique colour.  In this paper,  it is proved that PCFP $k$-colourability of digraphs is NP-complete,  for any $k >0$.  Nevertheless  for   ...  Read More

Defining the Tipping Point Based on Conditionally Convergent Series: Explaining the Indeterminacy

Mohammad Hosseini Moghaddam; Tahmineh Sahverdi

Volume 50, Issue 1 , June 2018, Pages 133-142

https://doi.org/10.22059/jac.2018.68630

Abstract
  Tipping Point refers to the moment when an adaption or infection sustains itself in network without further external inputs. Until now, studies have mainly focused on the occurrence of the Tipping Point and what it leads to rather than what precedes it. This paper explores the situation leading to the ...  Read More

$k$-Total prime cordial labeling of graphs

R Ponraj; J Maruthamani; R Kala

Volume 50, Issue 1 , June 2018, Pages 143-149

https://doi.org/10.22059/jac.2018.68651

Abstract
  In this paper we introduce a new graph labeling method called $k$-Total prime cordial. Let $G$ be a $(p,q)$ graph. Let $f:V(G)\to\{1,2, \ldots, k\}$ be a map where $k \in \mathbb{N}$ and $k>1$. For each edge $uv$, assign the label $gcd(f(u),f(v))$. $f$ is called $k$-Total prime cordial labeling of ...  Read More

https://doi.org/10.22059/jac.2018.68964

Abstract
  Yager family of t-norms is a parametric family of continuous nilpotent t-norms which is also one of the most frequently applied one. This family of t-norms is strictly increasing in its parameter and covers the whole spectrum of t-norms when the parameter is changed from zero to infinity. In this paper, ...  Read More
