An upper bound for the Z-spectral radius of adjacency tensors. [PDF]
Journal of Inequalities and Applications, 2018 Let H $\mathcal{H}$ be a k-uniform hypergraph on n vertices with degree sequence Δ=d1≥⋯≥dn=δ $\Delta=d_{1} \geq\cdots\geq d_{n}=\delta$. In this paper, in terms of degree di $d_{i}$, we give a new upper bound for the Z-spectral radius of the adjacency ...

Eigenvalues of the adjacency tensor on products of hypergraphs [PDF]
International Journal of Contemporary Mathematical Sciences, 2013 We consider the generalized notions of Cartesian and tensor products on m-uniform hypergraphs. The adjacency tensor is analogous to the adjacency matrix and two different notions of eigenvalues of the adjacency tensor on the products of hypergraphs are studied.

Anti-Adjacency Matrices of Certain Graphs Derived from Some Graph Operations [PDF]
Ratio Mathematica, 2023 If we go through the literature, one can find many matrices that are derived for a given simple graph. The one among them is the anti-adjacency matrix which is given as follows; The anti-adjacency matrix of a simple undirected graph $G$ with vertex set

Hyperspectral Image Dimension Reduction Using Weight Modified Tensor-Patch-Based Methods
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Dimension reduction (DR) addresses the problem known as the curse of dimensionality in myriad hyperspectral imagery applications. Although the spatial pattern may assist in the distinction between different land covers that have close spectral signatures,

Multi-Dimensional Quantum-like Resources from Complex Synchronized Networks [PDF]
EntropyRecent publications have introduced the concept of quantum-like (QL) bits, along with their associated QL states and QL gate operations, which emerge from the dynamics of complex, synchronized networks. The present work extends these ideas to multi-level

Quasi-Irreducibility of Nonnegative Biquadratic Tensors
MathematicsWhile the adjacency tensor of a bipartite 2-graph is a nonnegative biquadratic tensor, it is inherently reducible. To address this limitation, we introduce the concept of quasi-irreducibility in this paper.
