Fast Toeplitz eigenvalue computations, joining interpolation-extrapolation matrix-less algorithms and simple-loop conjectures: the preconditioned setting

Manuel Bogoya, Stefano Serra-Cappizano, Paris Vassalos

Under appropriate technical assumptions, the simple-loop theory allows to deduce various types of asymptotic expansions for the eigenvalues of Toeplitz matrices generate…

On a Boundary Updating Method for the Scalar Stefan Problem

Evangelos F. Magirou, Paraskevas Vassalos, Nikolaos Barakitis

We report on a general purpose method for the scalar Stefan problem inspired by the standard boundary updating method used in several existence proofs. By suitably modifying it we…

A Matrix-Less Method to Approximate the Spectrum and the Spectral Function of Toeplitz Matrices with Complex Eigenvalues

Sven-Erik Ekström, Paris Vassalos

It is known that the generating function of a sequence of Toeplitz matrices may not describe the asymptotic distribution of the eigenvalues of if is…
