Lower bound on minimum eigenvalue
WebMar 16, 2024 · Abstract. 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 … WebKofi: in your question you are asking for a lowerbound of the biggest eigenvalue. If the question is about the smallest, replace 1 by a big x in your example. – Mikael de la Salle Jul 20, 2013 at 7:44 Yes sorry, I fixed that mistake. But what happens if I replace the 1 with a large X in the example?

Web3.4 The Largest Eigenvalue, 1 We now examine 1 for graphs which are not necessarily regular. Let Gbe a graph, let d max be the maximum degree of a vertex in G, and let d ave be the average degree of a vertex in G. Lemma 3.4.1. d ave 1 d max: Proof. The lower bound follows by considering the Rayleigh quotient with the all-1s vector: 1 = max x ... WebA 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. Appl., 2014, 2014, 114) and Zhao and Sang (J. Inequal. Appl., 2016, 2016, 268).
WebJul 16, 2024 · M-eigenvalues of elasticity M-tensors play an important role in nonlinear elasticity and materials. In this paper, we present several new lower bounds for the minimum M-eigenvalue of elasticity M-tensors and propose numerical examples to illustrate the efficiency of the obtained results. WebDec 1, 2000 · In particular, tighter bounds have been introduced for the Dembo's lower bound of the minimal eigenvalue that had been widely applied [2]- [4], yet no tighter bound has …
