Fully computable a posteriori error bounds for eigenfunctions
approximation. Both algorithms apply well to the case of tight clusters and multiple eigenvalues, under the settings of target eigenvalue problems. Algorithm I is based on the Rayleigh quotient and the min-max principle th...

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...
