A note on the automorphism group of the Hamming graph [PDF]

open access: yesTransactions on Combinatorics, 2021
Let $m>1$ be an integer and $\Omega$ be an $m$-set‎. ‎The Hamming graph $H(n,m)$ has $\Omega ^{n}$ as its vertex-set‎, ‎with two vertices are adjacent if and only if they differ in exactly one coordinate‎.

Hamming-shifting graph of genomic short reads: Efficient construction and its application for compression.

open access: yesPLoS Computational Biology, 2021
Graphs such as de Bruijn graphs and OLC (overlap-layout-consensus) graphs have been widely adopted for the de novo assembly of genomic short reads. This work studies another important problem in the field: how graphs can be used for high-performance ...

Tree-Like Partial Hamming Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Tree-like partial cubes were introduced in [B. Brešar, W. Imrich, S. Klavžar, Tree-like isometric subgraphs of hypercubes, Discuss. Math. Graph Theory, 23 (2003), 227-240] as a generalization of median graphs.

Radio Graceful Hamming Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2016
For k ∈ ℤ+ and G a simple, connected graph, a k-radio labeling f : V (G) → ℤ+ of G requires all pairs of distinct vertices u and v to satisfy |f(u) − f(v)| ≥ k + 1 − d(u, v). We consider k-radio labelings of G when k = diam(G).

Hamming Distance Encoding Multihop Relation Knowledge Graph Completion

open access: yesIEEE Access, 2020
Knowledge graphs (KGs) play an important role in many real-world applications like information retrieval, question answering, relation extraction, etc. To reveal implicit knowledge from a knowledge graph (KG), viz.

Spectral Characterization of the Hamming Graphs [PDF]

open access: yesSSRN Electronic Journal, 2007
It is shown that the Hamming graph \(H(3,q)\) with diameter three is uniquely determined by its spectrum for \(q\geq 36\). It is also demonstrated that for given integer \(D\geq 2\), any graph cospectral with the Hamming graph \(H(D,q)\) is locally the disjoint union of \(D\) copies of the complete graph of size \(q-1\), for \(q\) large enough.

On induced subgraphs of the Hamming graph [PDF]

open access: yesJournal of Graph Theory, 2020
AbstractIn connection with his solution of the Sensitivity Conjecture, Hao Huang (arXiv: 1907.00847, 2019) asked the following question: Given a graph with high symmetry, what can we say about the smallest maximum degree of induced subgraphs of with vertices, where denotes the size of the largest independent set in ?

Semantic ECG hash similarity graph [PDF]

open access: yesScientific Reports
Graph-based methods have made significant progress in addressing the dependent correlations among ECG time series variables. However, most existing graph structures primarily focus on local similarity while overlooking global semantic correlation ...

Burning Hamming graphs

open access: yesGraphs and Combinatorics
The Hamming graph $H(n,q)$ is defined on the vertex set $[q]^n$ and two vertices are adjacent if and only if they differ in precisely one coordinate. Alon \cite{Alon} proved that the burning number of $H(n,2)$ is $\lceil\frac n2\rceil+1$. In this note we give a short proof of a fact that the burning number of $H(n,q)$ is $(1-\frac 1q)n+O(\sqrt{n\log n})

Sensitivity and Hamming graphs

open access: yesarXiv.org
For any $m\geq 3$ we show that the Hamming graph $H(n,m)$ admits an imbalanced partition into $m$ sets, each inducing a subgraph of low maximum degree. This improves previous results by Tandya and by Potechin and Tsang, and disproves the Strong $m$-ary Sensitivity Conjecture of Asensio, García-Marco, and Knauer. On the other hand, we prove their weaker
