Decomposing 10-Regular Graphs into Paths of Length 5

Discussiones Mathematicae Graph Theory, 2022
Let G be a 10-regular graph which does not contain any 4-cycles. In this paper, we prove that G can be decomposed into paths of length 5, such that every vertex is a terminal of exactly two paths.

An Improved Simulated Annealing Algorithm With Excessive Length Penalty for Fixed-Outline Floorplanning

IEEE Access, 2020
In addition to wirelength and area, modern floorplans need to consider various constraints such as fixed-outline. To handle the fixed-outline floorplanning optimization problem efficiently, we propose an improved simulated annealing (SA) algorithm, which

Discrete Mathematics

, 2022
In this volume, the authors present a self-contained introduction to discrete mathematics – the science of finite and countably infinite structures. In addition to taking a theoretical approach, they also include many practical exercises. The text covers a broad range of topics such as propositional logic, set theory as well as detailed treatments of ...

Generalized Hausdorff Operators on K̇α,qβ,pℝ and HK̇α,qβ,p,Nℝ in the Dunkl Settings

Journal of Function Spaces, 2021
In the present paper, we obtain some new results, and we generalize some known results for the Hausdorff operators. We have studied the generalized Hausdorff operators Hα,φ on the Dunkl-type homogeneous weighted Herz spaces K̇α,qβ,pℝ and Dunkl Herz-type ...

The extremal graphs with respect to their nullity

Journal of Inequalities and Applications, 2016
The nullity of a graph G, denoted by η ( G ) $\eta(G)$ , is the multiplicity of the eigenvalue zero of its adjacency matrix. In this paper, we determine all graphs with η ( G ) = n ( G ) − 2 m ( G ) − c ( G ) $\eta(G)=n(G) - 2m(G) -c(G)$ , where c ( G ) =

Independent resolving sets in graphs

AKCE 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

Bicyclic graphs with maximum sum of the two largest Laplacian eigenvalues

Journal 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

A hierarchy of maximal intersecting triple systems [PDF]

Opuscula 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.
