Toeplitz matrices for the study of the fractional Laplacian on a bounded interval
Philippe Rambour, Abdellatif Seghier
Toeplitz matrices for the study of the fractional Laplacian on a bounded interval. In this work we get a deep link between (--) ]0,1[ the fractional Laplacian on the interva…

Fractional differential operators and Toeplitz matrices
Philippe Rambour, Abdellatif Seghier
In this work we generalize to few fractional differential operators the method used to reverse differential operators by inverting a Toeplitz matrix. The i…

Maximal eigenvalue and norm of the product of Toeplitz matrices. Study of a particular case
Philippe Rambour
In this paper we describe the asymptotic behaviour of the spectral norm of the product of two finite Toeplitz matrices as the matrix dimension goes to the infinity. These Toeplitz…
