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 $H_{n} (f) = Y_{n} T_{n} (f)$ , where $T_{n} (f)$ is the $n \times n$ Toeplitz matrix generated by the function $f$ and $Y…

From asymptotic distribution and vague convergence to uniform convergence, with numerical applications

Giovanni Barbarino, Sven-Erik Ekström, Carlo Garoni +3

Let ${Λ_{n} = {λ_{1, n}, \dots, λ_{d_{n}, n}}}_{n}$ be a sequence of finite multisets of real numbers such that $d_{n} \to \infty$ as $n \to \infty$ , and let $f : Ω \subset R^{d} \to R$ …
