l1-Embeddability Under Gate-Sum Operation of Two l1-Graphs

open access: yesFrontiers in Physics, 2020
An l1-graph is one in which the vertices can be labeled by binary vectors such that the Hamming distance between two binary addresses is, to scale, the distance in the graph between the corresponding vertices. This study was designed to determine whether

On k-partitioning of Hamming graphs

open access: yesDiscrete Applied Mathematics, 1999
For a graph \(G=(V,E)\) a \(k\)-partition is a partition \(A=\{A_1, A_2, \dots, A_k \}\) of \(V\) such that \(||A_i|- |A_j||\leq 1\) for all \(i,j\in \{1,2,\dots, k\}\). A cut of partition \(A\) is a set of edges having ends in different sets of the partition.

Completely Transitive Codes in Hamming Graphs

open access: yesEuropean Journal of Combinatorics, 1999
A code \(C\) in the graph \(\Gamma\) is a non-empty subset of the vertex set \(V\) of \(\Gamma\). Completely transitive codes are a special class of completely regular codes. A code in the graph \(\Gamma\) is called a completely transitive code if there exists a subgroup \(G\) of the group of automorphisms of \(\Gamma\), such that each cell \(C_i\) in ...

Relation between spectra of Narain CFTs and properties of associated boolean functions

open access: yesJournal of High Energy Physics, 2022
Recently, the construction of Narain CFT from a certain class of quantum error correcting codes has been discovered. In particular, the spectral gap of Narain CFT corresponds to the binary distance of the code, not the genuine Hamming distance.

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.

On the Independence Graph of Hamming Graph

open access: yesIranian Journal of Mathematical Sciences and Informatics
Summary: The independence graph \(\operatorname{Ind}(G)\) of a graph \(G\) is the graph with vertices as maximum independent sets of \(G\) and two vertices are adjacent, if and only if the corresponding maximum independent sets are disjoint. In this work, we find the independence graph of Cartesian product of \(d\) copies of complete graphs \(K_q ...

Visual Understanding of Metabolic Pathways Across Organisms Using Layout in Two and a Half Dimensions

open access: yesJournal of Integrative Bioinformatics, 2004
We propose a method for visualizing a set of related metabolic pathways across organisms using 2 1/2 dimensional graph visualization. Interdependent, twodimensional layouts of each pathway are stacked on top of each other so that biologists get a full ...

Neighbour transitivity on codes in Hamming graphs

open access: yes, 2011
We consider a \emph{code} to be a subset of the vertex set of a \emph{Hamming graph}. In this setting a \emph{neighbour} of the code is a vertex which differs in exactly one entry from some codeword.

Retracts of Infinite Hamming Graphs

open access: yesJournal of Combinatorial Theory, Series B, 1997
A Hamming graph is a Cartesian product of complete graphs. We show that (finite or infinite) quasi-median graphs, which are a generalization of median graphs, are exactly the retracts of Hamming graphs. This generalizes a result of \textit{H. J. Bandelt} [J.
