| Chromatic Polynomials of Mixed Hypercyles |
2013 |
73 |
We color the vertices of each of the edges of a C-hypergraph (or cohypergraph) in such a way that at least two vertices receive the same color and in every proper coloring of a B-hypergraph (or bihypergraph), we forbid the cases when the vertices of ... |
| Chromatic Polynomials of Some Mixed Hypergraphs |

Motivated by a recent result of M. Walter [Electron. J. Comb. 16, No. 1, Research Paper R94, 16 p. (2009; Zbl 1186.05059)] concerning the chromatic polynomials of some hypergraphs, we present the chromatic polynomials of several (non-uniform) mixed h... |

The theory of mixed hypergraphs coloring has been first introduced by Voloshin in 1993 and it has been growing ever since. The proper coloring of a mixed hypergraph H = (X; C;D) is the coloring ofthe vertex set X so that no D??hyperedge is monochroma... |
| Domination and Dominion of Some Graphs |
2020 |
461 |
Given a simple undirected graph G = (V;E), a -set also known as dominating setis a subset S V such that for any vertex v 2 V , either v 2 S or a neighbor u of v is in S. Given G, the size of its -set, denoted by , is its domination number and the dom... |
| Dominion on Ladders |
2023 |
501 |
A grid graph G(m,n) is often used to model certain computer networking configurations.To investigate the ‘robustness’ of such network against an adversarial attack,we study two related parameters on its subgraph, called Ladder, which we denote byLn: ... |
| F-WORM colorings of some 2-trees: partition vectors |
2018 |
81 |
A collection of distinct subgraphs of a graphG = (V;E).An F-WORM coloring of G is the coloring of its vertices such that no copy of each subgraphFi 2 F is monochrome or rainbow. This generalizes the notion of F-WORMcoloring that was introduced recent... |

This thesis explores factors that influence traffic accidents focusing on location, severity, time, road condition, and weather factors. Using a nationwide traffic accident dataset found in Kaggle which contains Application Programming Interface (API... |
| Formulas for the computation of the Tutte polynomial of graphs with parallel classes |

We give some reduction formulas for computing the Tutte polynomial of any graph with parallelclasses. Several examples are given to illustrate our results. |
| Hall numbers of some complete k-partite graphs |
2011 |
99 |
The Hall number is a graph parameter closely related to the choice number. Here it is shown that the Hall numbers of the complete multipartite graphs K(m,2,?,2), m=2, are equal to their choice numbers. |

Throughout the course of time, technology has evolved and led to masscommunication throughout the world. One of the biggest types of communicationin today’s society is social media. Furthermore, it can be defined as avirtual community that allows use... |
| On the Choosability of Some Graphs |
2015 |
169 |
Suppose ch(G) and X(G) denote, respectively, the choice number and the chromatic number of a graph G = (V;E). If ch(G) = (G) then G is said to be chromatic-choosable. Recently, Reed et al. proved a conjecture by Ohba that states that G is chromatic c... |
