The Pascal Matrix, Commuting Tridiagonal Operators and Fourier Algebras

W. Riley Casper, Ignacio Zurrian

We consider the (symmetric) Pascal matrix, in its finite and infinite versions, and prove the existence of symmetric tridiagonal matrices commuting with it by giving explicit expre…

The restricted discrete Fourier transform

W. Riley Casper, Milen Yakimov

We investigate the restriction of the discrete Fourier transform $F_{N} : L^{2} (Z / N Z) \to L^{2} (Z / N Z)$ to the space $C_{a}$ of functions with…
