Low Diameter Graph Decompositions by Approximate Distance Computation [PDF]

open access: yes, 2019
In many models for large-scale computation, decomposition of the problem is key to efficient algorithms. For distance-related graph problems, it is often crucial that such a decomposition results in clusters of small diameter, while the probability that ...

Connectivity and tree structure in finite graphs [PDF]

open access: yes, 2013
Considering systems of separations in a graph that separate every pair of a given set of vertex sets that are themselves not separated by these separations, we determine conditions under which such a separation system contains a nested subsystem that ...

Claw-decomposition of Kneser graphs

open access: yesTransactions on Combinatorics, 2022
Summary: A claw is a star with three edges. The Kneser graph \(KG_{n, 2}\) is the graph whose vertices are the 2-subsets of an \(n\)-set, in which two vertices are adjacent if and only if their intersection is empty. In this paper, we prove that \(KG_{n, 2}\) is claw-decomposable, for all \(n\geq 6\).

Decomposition of complete graphs into connected unicyclic graphs with eight edges and pentagon

open access: yesIndonesian Journal of Combinatorics, 2019
A G-decomposition of the complete graph Kn is a family of pairwise edge disjoint subgraphs of Kn, all isomorphic to G, such that every edge of Kn belongs to exactly one copy of G.

Fast Spectral Approximation of Structured Graphs with Applications to Graph Filtering

open access: yesAlgorithms, 2020
To analyze and synthesize signals on networks or graphs, Fourier theory has been extended to irregular domains, leading to a so-called graph Fourier transform.

The approximate Loebl-Koml\'os-S\'os Conjecture II: The rough structure of LKS graphs [PDF]

open access: yes, 2016
This is the second of a series of four papers in which we prove the following relaxation of the Loebl-Komlos--Sos Conjecture: For every $\alpha>0$ there exists a number $k_0$ such that for every $k>k_0$ every $n$-vertex graph $G$ with at least $(\frac12+\

Decomposition of hypercube graphs into paths and cycles of length four

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
By a [Formula: see text]-decomposition of a graph G, we mean a partition of the edge set of G into p paths of length 4 and q cycles of length 4. In this paper, we give conditions for a [Formula: see text]-decomposition of the n-dimensional hypercube ...

Image Clustering Algorithm Based on Hypergraph Regularized Nonnegative Tucker Decomposition [PDF]

open access: yesJisuanji gongcheng, 2022
The internal geometry structure of high-dimensional data is ignored when nonnegative tensor decomposition is applied to image clustering.To solve this problem, we propose a Hypergraph regularized Nonnegative Tucker Decomposition(HGNTD) model by adding a ...
