The Completion Numbers of Hamiltonicity and Pancyclicity in Random Graphs [PDF]

open access: yesRandom Structures &Algorithms, Volume 66, Issue 2, March 2025., 2023
Let μ(G)$$ \mu (G) $$ denote the minimum number of edges whose addition to G$$ G $$ results in a Hamiltonian graph, and let μ^(G)$$ \hat{\mu}(G) $$ denote the minimum number of edges whose addition to G$$ G $$ results in a pancyclic graph.

Rainbow Pancyclicity in Graph Systems [PDF]

open access: greenThe Electronic Journal of Combinatorics, 2019
 Let $G_1,\ldots,G_n$ be graphs on the same vertex set of size $n$, each graph with minimum degree $\delta(G_i)\ge n/2$. A recent conjecture of Aharoni asserts that there exists a rainbow Hamiltonian cycle i.e. a cycle with edge set $\{e_1,\ldots,e_n\}$ such that $e_i\in E(G_i)$ for $1\leq i \leq n$.

Pancyclicity of Hamiltonian graphs [PDF]

open access: yesJournal of the European Mathematical Society, 2022
An n -vertex graph is Hamiltonian if it contains a cycle that covers all of its vertices, and it is pancyclic if it contains cycles of all lengths from 3 up to

Chvátal-Erdős condition for pancyclicity [PDF]

open access: goldJournal of the Association for Mathematical Research, 2023
An n-vertex graph is Hamiltonian if it contains a cycle that covers all of its vertices and it is pancyclic if it contains cycles of all lengths from 3 up to n. A celebrated meta-conjecture of Bondy states that every non-trivial condition implying Hamiltonicity also implies pancyclicity (up to possibly a few exceptional graphs).

Two-Disjoint-Cycle-Cover Pancyclicity of Dragonfly Networks

open access: yesMathematics
Interconnection networks (often modeled as graphs) are critical for high-performance computing systems, as they have significant impact on performance metrics like latency and bandwidth.

A generalization of Bondy’s pancyclicity theorem [PDF]

open access: goldCombinatorics, probability & computing, 2023
The \emph{bipartite independence number} of a graph $G$, denoted as $\tilde\alpha(G)$, is the minimal number $k$ such that there exist positive integers $a$ and $b$ with $a+b=k+1$ with the property that for any two sets $A,B\subseteq V(G)$ with $A=a$ and

Pancyclicity in the Cartesian Product (K9 −C9)N [PDF]

open access: greenSocial Science Research Network, 2022
A graph G on m vertices is pancyclic if it contains cycles of length l , 3 ≤ l ≤ m as subgraphs in G . The complete graph K 9 on 9 vertices with a cycle C 9 of length 9 deleted from K 9 is denoted by ( K 9 − C 9 ).

Toughness, Forbidden Subgraphs and Pancyclicity [PDF]

open access: hybridGraphs and Combinatorics, 2021
AbstractMotivated by several conjectures due to Nikoghosyan, in a recent article due to Li et al., the aim was to characterize all possible graphs H such that every 1-tough H-free graph is hamiltonian. The almost complete answer was given there by the conclusion that every proper induced subgraph H of $$K_1\cup P_4$$

Hamiltonicity and pancyclicity of superclasses of claw-free graphs

open access: diamondFilomat, 2023
A graph G is called to be fully cycle extendable graph [3] if each vertex of G belongs to a triangle and for any cycle C with |V(C)| < |V(G)| there exists a cycle C? in G such that V(C) ? V(C?) and |V(C?)| = |V(C)|+1. In this paper, we show that every
