Finite Riesz products and Ornstein non-inequalities on quantum tori

Christos P. Tantalakis, Michał Wojciechowski

We demonstrate a construction of products on the quantum torus $T_{θ}^{2}$ that generalises the usual construction of finite Riesz products on the commutative torus $\mathbb{T…

Eigenvalue asymptotics for a class of multi-variable Hankel matrices

Christos Panagiotis Tantalakis

A one-variable Hankel matrix $H_{a}$ is an infinite matrix $H_{a} = [a (i + j)]_{i, j \geq 0}$ . Similarly, for any $d \geq 2$ , a $d$ -variable Hankel matrix is defined as $H_{\mathbf{a}}=[\mathbf…
