The extreme eigenvalues of two types of random matrices
, 2021 The fluctuations of extreme eigenvalues of a large random matrix model is a central topic in random matrix theory, motivated by applications in principle component analysis, factor analysis, or signal detection problems.

Uniform approximation of eigenvalues in Laguerre and Hermite beta-ensembles by roots of orthogonal polynomials [PDF]
We derive strong uniform approximations for the eigenvalues in general Laguerre and Hermite beta-ensembles by showing that the maximal discrepancy between the suitably scaled eigenvalues and roots of orthogonal polynomials converges almost surely to zero

Estimates on the eigenvalues for some nonlinear ordinary differential operators [PDF]
, 1989 The nonlinear eigenvalue problem Lu+f(x,u)=λu in (a,b) , with u(a)=u(b)=0 , where Lu=−(p(x)u ′ ) ′ +q(x)u is the usual differential operator for Sturm-Liouville problems, f is continuous and such that f(x,0)=0 for all x , and λ is a real parameter ...

Bounded Eigenvalues of Fully Clamped and Completely Free Rectangular Plates [PDF]
, 2007 Exact solution to the vibration of rectangular plates is available only for plates with two opposite edges subject to simply supported conditions. Otherwise, they are analysed by using approximate methods. There are several approximate methods to conduct

On higher order eigenvalues of the spherical laplacian operator [PDF]
, 2010 In this paper, we use the boundary measurements of normalized eigenfunctions to estimate the variation of the corresponding eigenvalues. With this form, we can show that some eigenvalues, as functions of domain, possess monotonicity as the domain varies ...

Bifurcation of eigenvalues in nonlinear problems with antilinear symmetry [PDF]
, 2016 Many physical systems can be described by nonlinear eigenvalues and bifurcation problems with a linear part that is non-selfadjoint e.g. due to the presence of loss and gain.

Estimates for Eigenvalues of Schrodinger Operators with Complex-Valued Potentials
, 2016 New estimates for eigenvalues of non-self-adjoint multi-dimensional Schrodinger operators are obtained in terms of L (p) -norms of the potentials. The results cover and improve those known previously, in particular, due to Frank (Bull Lond Math Soc 43(4):

Science education in context: An overview and some observations [PDF]
, 2008 This book presents an international perspective of the influence of educational context on science education. By this we mean the context in which the teaching and learning takes place, rather than the use of a context-based approach to learning and ...
