Token Sliding on Split Graphs [PDF]

open access: yesTheory of Computing Systems, 2020
We consider the complexity of the Independent Set Reconfiguration problem under the Token Sliding rule. In this problem we are given two independent sets of a graph and are asked if we can transform one to the other by repeatedly exchanging a vertex that is currently in the set with one of its neighbors, while maintaining the set independent.

Split domination of splitted graphs

open access: yes, 2021
In this paper, we introduce and investigate some new splitted graphs called \(S(P_l); S(H_l); S(P^+_l ), S(P_loNK_1) .\) Also we discuss some splitted graphs and it's properties are obtained.

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 ...

On the Intersection Graphs Associeted to Posets

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2020
Let (P, ≤) be a poset with the least element 0. The intersection graph of ideals of P, denoted by G(P), is a graph whose vertices are all nontrivial ideals of P and two distinct vertices I and J are adjacent if and only if I ∩ J ≠ {0}.

Arbitrarily Partitionable {2K2, C4}-Free Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
A graph G = (V, E) of order n is said to be arbitrarily partitionable if for each sequence λ = (λ1, λ2, …, λp) of positive integers with λ1 +·…·+λp = n, there exists a partition (V1, V2, …, Vp) of the vertex set V such that Vi induces a connected ...

Computing the split domination number of grid graphs

open access: yesIndonesian Journal of Combinatorics, 2021
A set D - V is a dominating set of G if every vertex in V - D is adjacent to some vertex in D. The dominating number γ(G) of G is the minimum cardinality of a dominating set D.

Pebbling in Semi-2-Trees [PDF]

open access: yes, 2017
Graph pebbling is a network model for transporting discrete resources that are consumed in transit. Deciding whether a given configuration on a particular graph can reach a specified target is ${\sf NP}$-complete, even for diameter two graphs, and ...

Split-critical and uniquely split-colorable graphs [PDF]

open access: diamondDiscrete Mathematics & Theoretical Computer Science, 2010
Graphs and Algorithms The split-coloring problem is a generalized vertex coloring problem where we partition the vertices into a minimum number of split graphs. In this paper, we study some notions which are extensively studied for the usual vertex coloring and the cocoloring problem from the point of view of split-coloring, such as ...

Polarity on H-split graphs

open access: yesProcedia Computer Science, 2023
Given nonnegative integers, $s$ and $k$, an $(s,k)$-polar partition of a graph $G$ is a partition $(A,B)$ of $V_G$ such that $G[A]$ and $\overline{G[B]}$ are complete multipartite graphs with at most $s$ and $k$ parts, respectively. If $s$ or $k$ is replaced by $\infty$, it means that there is no restriction on the number of parts of $G[A]$ or ...
