Minimum eigenvalues for positive, Rockland operators [PDF]
Let L L be a positive, Rockland operator of homogeneous degree γ \gamma . The minimum eigenvalue of d π ( L ) d\pi (L) increases as the γ \gamma th power of the homogeneous distance from the origin of the orbit corresponding to π \pi

Extended Perron complements of M-matrices
This paper aims to consider the extended Perron complements for the collection of M-matrices. We first exhibit the connection between the extended Perron complements of M-matrices and nonnegative matrices.

Graph diameter, eigenvalues, and minimum-time consensus [PDF]
We consider the problem of achieving average consensus in the minimum number of linear iterations on a fixed, undirected graph. We are motivated by the task of deriving lower bounds for consensus protocols and by the so-called "definitive consensus conjecture" which states that for an undirected connected graph G with diameter D there exist D matrices ...

The dual eigenvalue problems of the conformable fractional Sturm–Liouville problems
In this paper, we are concerned with the eigenvalue gap and eigenvalue ratio of the Dirichlet conformable fractional Sturm–Liouville problems. We show that this kind of differential equation satisfies the Sturm–Liouville property by the Prüfer ...

New lower bounds of the minimum eigenvalue for the Fan product of several M-matrices
In this study, we generalize the definition of the Fan product of two M-matrices to any $ k $ M-matrices $ {{A}_{1}}, {{A}_{2}}, \cdots, {{A}_{k}} $ of order $ n $.

SNR walls in eigenvalue-based spectrum sensing
Various spectrum sensing approaches have been shown to suffer from a so-called signal-to-noise ratio (SNR)-wall, an SNR value below which a detector cannot perform robustly no matter how many observations are used. Up to now, the eigenvalue-based maximum-

Maxima of the Q-index: graphs without long paths [PDF]
This paper gives tight upper bound on the largest eigenvalue q(G) of the signless Laplacian of graphs with no paths of given order. The main ingredient of our proof is a stability result of its own interest, about graphs with large minimum degree and ...

On the Neumann eigenvalues for second-order Sturm–Liouville difference equations
The paper is concerned with the Neumann eigenvalues for second-order Sturm–Liouville difference equations. By analyzing the new discriminant function, we show the interlacing properties between the periodic, antiperiodic, and Neumann eigenvalues ...

Scaling Theory of Conduction Through a Normal-Superconductor Microbridge [PDF]
The length dependence is computed of the resistance of a disordered normal-metal wire attached to a superconductor. The scaling of the transmission eigenvalue distribution with length is obtained exactly in the metallic limit, by a transformation onto ...
