Language: English
Authors: Voß, Heinrich 
Keywords: eigenvalue problem; Lanczos method; Toeplitz matrix; symmetry properties

Abstract (english): 
In this note we study a variant of the inverted Lanczos method which computes eigenvalue approximates of a symmetric matrix A from the projection to a Krylov space of A method at least as long as reorthogonalization is not required. The method is applied to the problem of determining the smallest eigenvalue of a symmetric Toeplitz matrix. It is accelerated taking advantage of symmetry properties of the corresponding eigenvector.
