Splitting Edge Partitions of Graphs

open access: yesMathematica Pannonica, 2023
In a typical maximum clique search algorithm when optimality testing is inconclusive a forking takes place. The instance is divided into smaller ones. This is the branching step of the procedure. In order to ensure a balanced work load for the processors for parallel algorithms it is essential that the resulting smaller problems are do not overly vary ...

Classical simulation of quantum many-body systems with a tree tensor network [PDF]

open access: yes, 2006
We show how to efficiently simulate a quantum many-body system with tree structure when its entanglement is bounded for any bipartite split along an edge of the tree.

Graph Equations for Line Graphs, Jump Graphs, Middle Graphs, Splitting Graphs And Line Splitting Graphs

open access: yesMapana - Journal of Sciences, 2010
For a graph G, let G, L(G), J(G) S(G), L,(G) and M(G) denote Complement, Line graph, Jump graph, Splitting graph, Line splitting graph and Middle graph respectively. In this paper, we solve the graph equations L(G) =S(H), M(G) = S(H), L(G) = LS(H), M(G) =LS(H), J(G) = S(H), M(G) = S(H), J(G) = LS(H) and M(G) = LS(G).

Split Legendary Domination in graphs

open access: yesRatio Mathematica
Harary and Norman introduced the line graph L(G) . We introduced the legendary domination number by combining the domination concept both in graph and its line graph.

Universal graphs and universal permutations

open access: yes, 2013
Let $X$ be a family of graphs and $X_n$ the set of $n$-vertex graphs in $X$. A graph $U^{(n)}$ containing all graphs from $X_n$ as induced subgraphs is called $n$-universal for $X$.

On fully split lacunary polynomials in finite fields [PDF]

open access: yes, 2011
We estimate the number of possible types degree patterns of $k$-lacunary polynomials of degree $t < p$ which split completely modulo $p$. The result is based on a combination of a bound on the number of zeros of lacunary polynomials with some graph ...

Edge Coloring of Split Graphs

open access: yesElectronic Notes in Discrete Mathematics, 2008
Abstract A split graph is a graph whose vertex set admits a partition into a stable set and a clique. The chromatic indexes for some subsets of split graphs, such as split graphs with odd maximum degree and split-indifference graphs, are known. However, for the general class, the problem remains unsolved.

Radio labeling of biconvex split graphs

open access: yesAKCE International Journal of Graphs and Combinatorics
A radio labeling of a graph G is a function [Formula: see text] such that for every pair of distinct vertices [Formula: see text], where diam(G) denotes the diameter of the graph and d(u, v) is the distance between the vertices u and v.

Monadic second-order definable graph orderings [PDF]

open access: yes, 2014
We study the question of whether, for a given class of finite graphs, one can define, for each graph of the class, a linear ordering in monadic second-order logic, possibly with the help of monadic parameters.

Characterizations for split graphs and unbalanced split graphs

open access: yes, 2021
We introduce a characterization for split graphs by using edge contraction. Then, we use it to prove that any ($2K_{2}$, claw)-free graph with $α(G) \geq 3$ is a split graph. Also, we apply it to characterize any pseudo-split graph. Finally, by using edge contraction again, we characterize unbalanced split graphs which we use to characterize the ...
