Moving average network examples for asymptotically stable periodic orbits of monotone maps

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
For a certain type of discrete-time nonlinear consensus dynamics, asymptotically stable periodic orbits are constructed. Based on a simple ordinal pattern assumption, the Frucht graph, two Petersen septets, hypercubes, a technical class of circulant ...

Methods of Sparse Measurement Matrix Optimization for Compressed Sensing

open access: yesIET Signal Processing, Volume 2025, Issue 1, 2025.
In compressed sensing (CS), a sparse measurement matrix with few nonzero entries is more competitive than a dense matrix in reducing the number of multiplication units. Recent studies indicate that an optimized measurement matrix having low coherence with a specified dictionary can significantly improve the reconstruction performance.

Mathematical Properties of the Hyperbolicity of Circulant Networks

open access: yesAdvances in Mathematical Physics, 2015
If X is a geodesic metric space and x1,x2,x3∈X, a geodesic triangle   T={x1,x2,x3} is the union of the three geodesics [x1x2], [x2x3], and [x3x1] in X.

C-Product Toolbox: A Computational Package for Third‐Order Tensor Operations Based on the Reduced c‐Product

open access: yesComputational and Mathematical Methods, Volume 2025, Issue 1, 2025.
This paper introduces the C-Product Toolbox, a new computational package available for MATLAB and Python, designed to perform operations on third‐order tensors using a tensor product known as the reduced c‐product. The reduced c‐product is a variant of the known c‐product, a tensor product based on the discrete cosine transform and belonging to a ...

A Formula for the Energy of Circulant Graphs with Two Generators

open access: yesJournal of Applied Mathematics, 2016
We derive closed formulas for the energy of circulant graphs generated by 1 and γ, where γ⩾2 is an integer. We also find a formula for the energy of the complete graph without a Hamilton cycle.

Harmonic–Arithmetic Index for the Generalized Mycielskian Graphs and Graphenes With Curvilinear Regression Models of Benzenoid Hydrocarbons

open access: yesComputational and Mathematical Methods, Volume 2025, Issue 1, 2025.
The generalized Mycielskian graphs are known for their advantageous properties employed in interconnection networks in parallel computing to provide efficient and optimized network solutions. This paper focuses on investigating the bounds and computation of the harmonic–arithmetic index of the generalized Mycielskian graph of path graph, cycle graph ...

Minimum Feedback Vertex Sets in Distance Graphs and Circulant Graphs

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
For a set D⊂ Z n, the distance graph P n (D) has Z n as its vertex set and the edges are between vertices i and j with |i-j|∈D. The circulant graph C n (D) is defined analogously by considering operations modulo n.

Longest Induced Cycles in Circulant Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2005
In this paper we study the length of the longest induced cycle in the unit circulant graph $X_n = Cay({\Bbb Z}_n; {\Bbb Z}_n^*)$, where ${\Bbb Z}_n^*$ is the group of units in ${\Bbb Z}_n$. Using residues modulo the primes dividing $n$, we introduce a representation of the vertices that reduces the problem to a purely combinatorial question of ...

Colouring Clique-Hypergraphs of Circulant Graphs

open access: yesGraphs and Combinatorics, 2008
A clique coloring of a graph \(G\) is a coloring of the vertices of \(G\) so that no maximal clique of size at least two is monochromatic. The clique hypergraph, \(\mathcal{H}(G)\), of a graph \(G\) has \(V(G)\) as its set of vertices and the maximal cliques of \(G\) as its hyperedges. A vertex coloring of \(\mathcal{H}(G)\) is a clique coloring of \(G\
