Hyperspectral Image Super-Resolution Algorithm Based on Graph Regular Tensor Ring Decomposition

open access: yesRemote Sensing, 2023
This paper introduces a novel hyperspectral image super-resolution algorithm based on graph-regularized tensor ring decomposition aimed at resolving the challenges of hyperspectral image super-resolution.

α_{2}-labeling of graphs [PDF]

open access: yesOpuscula Mathematica, 2009
We show that if a graph \(G\) on \(n\) edges allows certain special type of rosy labeling (a.k.a. \(\rho\)-labeling), called \(\alpha_2\)-labeling, then for any positive integer \(k\) the complete graph \(K_{2nk+1}\) can be decomposed into copies of \(G\)

Optimizing tree decompositions in MSO [PDF]

open access: yesLogical Methods in Computer Science, 2022
The classic algorithm of Bodlaender and Kloks [J. Algorithms, 1996] solves the following problem in linear fixed-parameter time: given a tree decomposition of a graph of (possibly suboptimal) width k, compute an optimum-width tree decomposition of the ...

On tree-decompositions of one-ended graphs [PDF]

open access: yes, 2018
A graph is one-ended if it contains a ray (a one way infinite path) and whenever we remove a finite number of vertices from the graph then what remains has only one component which contains rays. A vertex $v$ {\em dominates} a ray in the end if there are

The Spectrum Problem for the Connected Cubic Graphs of Order 10

open access: yesDiscussiones Mathematicae Graph Theory, 2021
We show that if G is a connected cubic graph of order 10, then there exists a G-decomposition of Kv if and only if v ≣ 1 or 10 (mod 15) except when v = 10 and G is one of 5 specific graphs.

A C3 Magic Decomposition on Friendship Graph with Odd Order

open access: yesJurnal Ilmu Dasar, 2022
Let G = (V,E) is graph with a non-empty set V containing vertices and a set of edges E. Also note that if H = {H_i⊆G_i = 1,2,3,...,n} is a collection of subgraphs from G with H_i≅Hj,i ≠ j.

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.

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 ...
