Bicyclic graphs with maximum sum of the two largest Laplacian eigenvalues

open access: yesJournal of Inequalities and Applications, 2016
Let G be a simple connected graph and S 2 ( G ) $S_{2}(G)$ be the sum of the two largest Laplacian eigenvalues of G. In this paper, we determine the bicyclic graph with maximum S 2 ( G ) $S_{2}(G)$ among all bicyclic graphs of order n, which confirms the

Independent resolving sets in graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let be a connected graph. Let be a subset of V with an order imposed on W. The k-vector is called the resolving vector of v with respect to W. The set W is called a resolving set if for any two distinct vertices In this paper we investigate the existence

Unified Contamination-Aware Routing Method Considering Realistic Washing Capacity Constraint in Digital Microfluidic Biochips

open access: yesIEEE Access, 2020
To fully utilize the dynamic reconfigurability of digital microfluidic biochips, most of electrodes would be shared by different droplets. Thus, contaminations caused by liquid residues among droplets are inevitable which lead to lethal errors in ...

Teaching of Discrete Mathematics [PDF]

open access: yes, 2002
This paper presents an alternative methodology of development for the discipline of Discrete Mathematics offered to courses in the area of computation. It explores the availability of new teaching tools and programming languages. This way, we try to stimulate and provide students with an environment in which they can reach better results in order that ...

A hierarchy of maximal intersecting triple systems [PDF]

open access: yesOpuscula Mathematica, 2017
We reach beyond the celebrated theorems of Erdȍs-Ko-Rado and Hilton-Milner, and a recent theorem of Han-Kohayakawa, and determine all maximal intersecting triples systems.

Equivalence of K-functionals and modulus of smoothness generated by a Dunkl type operator on the interval $(-1, 1)$

open access: yesComptes Rendus. Mathématique, 2023
Our aim in this paper is to show that the modulus of smoothness and the $K$-functionals constructed from the Sobolev-type space corresponding to the Dunkl operator are equivalent on the interval $(-1,1)$.

Discrete mathematics

open access: yes, 2020
The purpose of the present work is to provide short and supple teaching notes for a $30$ hours introductory course on elementary \textit{Enumerative Algebraic Combinatorics}. We fully adopt the \textit{Rota way}. The themes are organized into a suitable sequence that allows us to derive any result from the preceding ones by elementary processes ...

On Generalized Jacobsthal and Jacobsthal–Lucas Numbers

open access: yesAnnales Mathematicae Silesianae, 2022
Jacobsthal numbers and Jacobsthal–Lucas numbers are some of the most studied special integer sequences related to the Fibonacci numbers. In this study, we introduce one parameter generalizations of Jacobsthal numbers and Jacobsthal–Lucas numbers.
