Novel concepts in linear Diophantine fuzzy graphs with an application [PDF]
Proceedings of the Estonian Academy of SciencesThe linear Diophantine fuzzy graph (LDFG) notion serves as a new mathematical approach for the ambiguity and uncertainty modeling in decision-making issues. An LDFG eliminates the strict limitations of various existing graphs. The energy concept in graph

Interlacing eigenvalues and graphs [PDF]
Linear Algebra and its Applications, 1995 A survey paper to various kinds of applications of eigenvalue interlacing to matrices associated with graphs. Bounds are obtained for characteristic numbers of graphs, such as the size of maximal (co)clique, the chromatic number, the diameter, and the bandwidth, in terms of the eigenvalues of the standard adjacency matrix or the Laplacian matrix.

Advanced Optical Materials, EarlyView.Omni‐polarizers that pull all input polarization states to an elliptical or linear polarization can be made using highly resonant bi‐layer metasurfaces. The ellipticity of the selected polarization can be controlled by choosing the layer separation.

Representation of the norming constants by two spectra
Electronic Journal of Differential Equations, 2010 The representation of the norming constants by 2 spectra was studied by Levitan, Gasymov (and others) for the Sturm-Liouville problem with boundary conditions $y(0)cosalpha +y'(0)sinalpha=0$, $y(pi)coseta+y'(pi)sineta =0$, when $sin alpha eq 0$ and $

Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology
Advanced Photonics Research, EarlyView.This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Riesz bases generated by the spectra of Sturm-Liouville problems
Electronic Journal of Differential Equations, 2013 Let ${lambda _n^2} _{n = 0}^infty$ be the spectra of a Sturm-Liouville problem on $[0,pi ]$. We investigate the question: Do the systems ${ cos(lambda_nx)} _{n = 0}^infty$ or ${ sin(lambda_n x)} _{n = 0}^infty$ form Riesz bases in ${L^2}[0,pi ]$? The

Non‐Hermitian Topological Lattice Photonics: An Analytic Perspective
Advanced Photonics Research, EarlyView.This review establishes exact analytical solutions for non‐Hermitian Hatano–Nelson, Su–Schrieffer–Heeger, and generalized Rice–Mele models. We demonstrate non‐Hermitian skin effects via point‐gap topology, hybrid skin‐topological edge states in 2D lattices, and spin‐polarized boundary modes governed by dual bulk‐boundary correspondence.

Eigenvalues for radially symmetric non-variational fully nonlinear operators [PDF]
, 2009 In this paper we present an elementary theory about the existence of eigenvalues for fully nonlinear radially symmetric 1-homogeneous operators. A general theory for first eigenvalues and eigenfunctions of 1-homogeneous fully nonlinear operators exists ...
