Forbidden Induced Subgraphs of Power Graphs of Finite Groups

open access: yes, 2023
For different algebraic structures like groups, semigroups, rings, vector spaces, etc, we can prescribe various graph structures. The power graph is one such major graph representation which was initially defined for semigroups using the power ...

Forbidden subgraph characterization of (P3-free, K3-free)-colourable cographs [PDF]

open access: yes, 2018
A (P3-free, K3-free)-colouring of a graph G = (V, E) is a partition of V = A ∪ B such that G[A] is P3-free and G[B] is K3-free. This problem is known to be NP-complete even when restricted to planar graphs and perfect graphs.

Characterization of graphs dominated by induced paths

open access: yes, 2007
We give a characterization, in terms of forbidden induced subgraphs, of those graphs in which every connected induced subgraph has a dominating induced path on at most k vertices (k⩾3).

Forbidden Induced Subgraphs in Iterative Higher Order Line Graphs

open access: yes
Let $G$ be a simple finite connected graph. The line graph $L(G)$ of graph $G$ is the graph whose vertices are the edges of $G$, where $ef \in E(L(G))$ when $e \cap f \neq \emptyset$. Iteratively, the higher order line graphs are defined inductively as $L^1(G) = L(G)$ and $L^n(G) = L(L^{n-1}(G))$ for $n \geq 2$.
