Spectral properties of flipped Toeplitz matrices
Giovanni Barbarino, Sven-Erik Ekström, Carlo Garoni +3
We study the spectral properties of flipped Toeplitz matrices of the form , where is the Toeplitz matrix generated by the function and $Y…
From asymptotic distribution and vague convergence to uniform convergence, with numerical applications
Giovanni Barbarino, Sven-Erik Ekström, Carlo Garoni +3
Let be a sequence of finite multisets of real numbers such that as , and let …
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…
