Generalized Turán Problems for Complete Bipartite Graphs

open access: yesGraphs and Combinatorics, 2022
For graphs H, F and integer n, the generalized Turán number ex(n, H, F) denotes the maximum number of copies of H that an F-free n-vertex graph can have. We study this parameter when both H and F are complete bipartite graphs.

Graceful labeling of triangular extension of complete bipartite graph

open access: yesElectronic Journal of Graph Theory and Applications, 2019
For positive integers m ,  n , K m ,  n represents the complete bipartite graph. We name the graph G  =  K m ,  n  ⊙  K 2 as triangular extension of complete bipartite graph K m ,  n , since there is a triangle hanging from every vertex of K m ,  n .

Bipartite Ramsey numbers involving stars, stripes and trees

open access: yesElectronic Journal of Graph Theory and Applications, 2013
The Ramsey number R(m, n) is the smallest integer p such that any blue-red colouring of the edges of the complete graph Kp forces the appearance of a blue Km or a red Kn.

Local equivalence of complete bipartite and repeater graph states [PDF]

open access: yesPhysical Review A, 2018
Classifying locally equivalent graph states, and stabilizer states more broadly, is a significant problem in the theories of quantum information and multipartite entanglement.

Overlapping Community Detecting Based on Complete Bipartite Graphs in Micro-Bipartite Network Bi-Egonet

open access: yesIEEE Access, 2019
Community detection has become a hot topic in complex networks. It plays an important role in information recommendation and public opinion control. Bipartite network, as a special complex network, reflects the characteristics of a kind of network in our

On the r-dynamic coloring of subdivision-edge coronas of a path

open access: yesAIMS Mathematics, 2020
This paper deals with the r-dynamic chromatic number of the subdivision-edge corona of a path and exactly one of the following nine types of graphs: a path, a cycle, a wheel, a complete graph, a complete bipartite graph, a star, a double star, a fan ...

Algebraic properties of the binomial edge ideal of a complete bipartite graph [PDF]

open access: yes, 2013
Let JG denote the binomial edge ideal of a connected undirected graph on n vertices. This is the ideal generated by the binomials xiyj − xjyi, 1 ≤ i < j≤ n, in the polynomial ring S = K[x1, . . . , xn, y1, . . . , yn] where {i, j} is an edge of G.

The Bipartite-Splittance of a Bipartite Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2019
A bipartite-split graph is a bipartite graph whose vertex set can be partitioned into a complete bipartite set and an independent set. The bipartite- splittance of an arbitrary bipartite graph is the minimum number of edges to be added or removed in ...

Bounds for the Kirchhoff Index of Bipartite Graphs

open access: yesJournal of Applied Mathematics, 2012
A -bipartite graph is a bipartite graph such that one bipartition has m vertices and the other bipartition has n vertices. The tree dumbbell consists of the path together with a independent vertices adjacent to one pendent vertex of and b independent ...

Edge condition for hamiltonicity in balanced tripartite graphs [PDF]

open access: yesOpuscula Mathematica, 2009
A well-known theorem of Entringer and Schmeichel asserts that a balanced bipartite graph of order \(2n\) obtained from the complete balanced bipartite \(K_{n,n}\) by removing at most \(n-2\) edges, is bipancyclic.
