H$^+$-Eigenvalues of Laplacian and Signless Laplacian Tensors [PDF]
, 2013 We propose a simple and natural definition for the Laplacian and the signless Laplacian tensors of a uniform hypergraph. We study their H$^+$-eigenvalues, i.e., H-eigenvalues with nonnegative H-eigenvectors, and H$^{++}$-eigenvalues, i.e., H-eigenvalues ...

Pucci eigenvalues on geodesic balls
, 2016 We study the eigenvalue problem for the Riemannian Pucci operator on geodesic balls. We establish upper and lower bounds for the principal Pucci eigenvalues depending on the curvature, extending Cheng's eigenvalue comparison theorem for the Laplace ...

Nonlocal Conduction in a Metawire
Advanced Materials, Volume 37, Issue 13, April 2, 2025.A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

Comparison results for eigenvalues of curlcurl operator and Stokes operator [PDF]
, 2018 This paper mainly establishes comparison results for eigenvalues of $\curl\curl$ operator and Stokes operator. For three-dimensional simply connected bounded domains, the $k$-th eigenvalue of $\curl\curl$ operator under tangent boundary condition or normal boundary condition is strictly smaller than the $k$-th eigenvalue of Stokes operator.

Spectral characterizations of anti-regular graphs [PDF]
Linear Algebra and Its Applications, Vol. 557, pp. 84-104, 2018, 2018 We study the eigenvalues of the unique connected anti-regular graph $A_n$. Using Chebyshev polynomials of the second kind, we obtain a trigonometric equation whose roots are the eigenvalues and perform elementary analysis to obtain an almost complete characterization of the eigenvalues.

Eigenvalues and perfect matchings [PDF]
Linear Algebra and its Applications, 2005 AbstractWe give sufficient conditions for existence of a perfect matching in a graph in terms of the eigenvalues of the Laplacian matrix. We also show that a distance-regular graph of degree k is k-edge-connected.

Advanced Materials, EarlyView.Single‐layer magnetization switching with a small critical current density of ≈106 A cm−2 is demonstrated. The strong intrinsic spin Hall effect, causing the switching, is induced by the synergy of the inherent spin‐orbit coupling and the spontaneous oxygen octahedral rotation in SrRuO3.The findings highlight the immense potential for realizing ...

Shape optimization for an elliptic operator with infinitely many positive and negative eigenvalues
Advances in Nonlinear Analysis, 2018 This paper deals with an eigenvalue problem possessing infinitely many positive and negative eigenvalues. Inequalities for the smallest positive and the largest negative eigenvalues, which have the same properties as the fundamental frequency, are ...
