Exact Minimum Eigenvalue Distribution of an Entangled Random Pure State [PDF]

open access: yesJournal of Statistical Physics, 2008
A recent conjecture regarding the average of the minimum eigenvalue of the reduced density matrix of a random complex state is proved. In fact, the full distribution of the minimum eigenvalue is derived exactly for both the cases of a random real and a ...

Several new inequalities for the minimum eigenvalue of M-matrices [PDF]

open access: yesJournal of Inequalities and Applications, 2016
Several convergent sequences of the lower bounds for the minimum eigenvalue of M-matrices are given. It is proved that these sequences are monotone increasing and improve some existing results.

New bounds for the minimum eigenvalue of M-matrices

open access: yesOpen Mathematics, 2016
Some new bounds for the minimum eigenvalue of M-matrices are obtained. These inequalities improve existing results, and the estimating formulas are easier to calculate since they only depend on the entries of matrices.

Graph diameter, eigenvalues, and minimum-time consensus [PDF]

open access: yesAutomatica, 2014
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

open access: yesBoundary Value Problems, 2021
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 ...

Minimum number of distinct eigenvalues of graphs [PDF]

open access: yesThe Electronic Journal of Linear Algebra, 2013
The minimum number of distinct eigenvalues, taken over all real symmetric matrices compatible with a given graph $G$, is denoted by $q(G)$. Using other parameters related to $G$, bounds for $q(G)$ are proven and then applied to deduce further properties of $q(G)$. It is shown that there is a great number of graphs $G$ for which $q(G)=2$.
