An Eigenvalue Symmetric Matrix Contractor
We propose an eigenvalue contractor for symmetric matrices. Given a symmetric interval matrix A and an interval approximation of its eigenvalue sets the contractor reduces the entries of A such that no matrix with eigenvalues

Estimates of the principal eigenvalue of the p-Laplacian
We provide estimates from below and from above for the principal eigenvalue of the p-Laplacian on a bounded domain. We apply these estimates to study the asymptotic behavior of the principal eigenvalue for p ? +oo....

Half-linear eigenvalue problem: Limit behavior of the first eigenvalue for shrinking interval
We investigate the limit behavior of the first eigenvalue of the half-linear eigenvalue problem when the length of the interval tends to zero. We show that the important role is played by the limit behavior of ratios of primitive fu...

On the Variational Eigenvalues Which Are Not of Ljusternik-Schnirelmann Type
We discuss nonlinear homogeneous eigenvalue problems and the variational characterization of their eigenvalues. We focus on the Ljusternik-Schnirelmann method, present-Fischerminimaxprinciple in the linear case. At the end we presen...
