Sharp Bounds on the Minimum M-Eigenvalue of Elasticity M-Tensors

open access: yesMathematics, 2020
The M-eigenvalue of elasticity M-tensors play important roles in nonlinear elastic material analysis. In this paper, we establish an upper bound and two sharp lower bounds for the minimum M-eigenvalue of elasticity M-tensors without irreducible ...

New bounds for the minimum eigenvalue of 𝓜-tensors

open access: yesOpen Mathematics, 2017
A new lower bound and a new upper bound for the minimum eigenvalue of an 𝓜-tensor are obtained. It is proved that the new lower and upper bounds improve the corresponding bounds provided by He and Huang (J. Inequal.

Inequalities for the minimum eigenvalue of M-matrices

open access: yesThe Electronic Journal of Linear Algebra, 2010
Let A be a nonsingular M-matrix, and τ(A) denote its minimum eigenvalue. Shivakumar et al. [SIAM J. Matrix Anal. Appl., 17(2):298-312, 1996] presented some bounds of τ(A) when A is a weakly chained diagonally dominant M-matrix. The present paper establishes some new bounds of τ(A) for a general nonsingular M-matrix A.

Two new lower bounds for the minimum eigenvalue of M-tensors [PDF]

open access: yesJournal of Inequalities and Applications, 2016
Two new lower bounds for the minimum eigenvalue of an irreducible M-tensor are given. It is proved that the new lower bounds improve the corresponding bounds obtained by He and Huang (J. Inequal. Appl. 2014:114, 2014).

Bounds and optimization of the minimum eigenvalue for a vibrating system [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
We consider the problem of the oscillation of a string fixed at one end with a mass connected to a spring at the other end. The problem of minimizing the first eigenvalue of the system subject to a fixed total mass constraint is investigated.

An eigenvalue localization set for tensors and its applications

open access: yesJournal of Inequalities and Applications, 2017
A new eigenvalue localization set for tensors is given and proved to be tighter than those presented by Li et al. (Linear Algebra Appl. 481:36-53, 2015) and Huang et al. (J. Inequal. Appl. 2016:254, 2016).

Existence of a principal eigenvalue for the Tricomi problem

open access: yesElectronic Journal of Differential Equations, 2000
The existence of a principal eigenvalue is established for the Tricomi problem in normal domains; that is, the existence of a positive eigenvalue of minimum modulus with an associated positive eigenfunction.

A lower bound sequence for the minimum eigenvalue of Hadamard product of an $M$-matrix and its inverse [PDF]

open access: yes, 2022
summary:We propose a lower bound sequence for the minimum eigenvalue of Hadamard product of an $M$-matrix and its inverse, in terms of an $S$-type eigenvalues inclusion set and inequality scaling techniques. In addition, it is proved that the lower bound
