The computation of selected eigenvalues and eigenvectors of a symmetric (Hermitian) matrix is an important subtask in many contexts, for example in electronic structure calculations. If a significant portion of the eigensystem is required then typica

The recent amplification DDoS attacks have swamped victims with huge loads of undesired traffic, sometimes even exceeding hundreds of Gbps attack bandwidth. We analyze these amplification attacks in more detail. First, we inspect the reconnaissance s

Summary We consider subspace iteration (or projection-based) algorithms for computing those eigenvalues (and associated eigenvectors) of a Hermitian matrix that lie in a prescribed interval. For the case that the projector is approximated with polyno

We consider the FEAST eigensolver, introduced by Polizzi in 2009 [5]. We describe an improvement concerning the reliability of the algorithm and discuss an application in the solution of eigenvalue problems from graphene modeling. (© 2014 Wiley-VCH
