A Variation Norm Carleson Theorem Along the Primes

Anastasios Fragkos, Ben Krause, Nazar Miheisi +1

Let $Λ$ denote the von Mangoldt function; we prove that for each $r > 2$ , there exist constants \[ r' < \mathbf{c}(r) < 2 < \mathbf{C}(r), \qquad \lim_{r \to \infty} \mathbf{c}(r)…

Uniqueness sets for functions of Dirichlet-type with restricted Taylor coefficients

Nazar Miheisi, Daniel Seco

Let $H$ be a reproducing kernel Hilbert space over the unit disk $D$ , where analytic monomials span a dense subset. Given $N \subseteq Z_{+}$ and $Λ\subset…

Szegő Limit Theorem for Truncated Toeplitz Operators

Nazar Miheisi, Ryan O'Loughlin

We discuss generalizations of the Szegő Limit Theorem to truncated Toeplitz operators. In particular, we consider compressions of Toeplitz operators to an increasing sequence of fi…

Completeness of systems of inner functions

Nazar Miheisi

For two inner functions $ϑ, φ \in H^{\infty}$ , we give a simple sufficient condition for the system $ϑ^{m}, φ^{n}$ , $m, n \in Z$ , to be complete in the weak- $^{*}$ to…

Averages with the Gaussian divisor: Weighted Inequalities and the Pointwise Ergodic Theorem

Christina Giannitsi, Nazar Miheisi, Hamed Mousavi

We discuss the Pointwise Ergodic Theorem for the Gaussian divisor function $d (n)$ , that is, for a measure preserving $Z [i]$ action $T$ , the limit $$\lim_{N\rightarrow \inft…

When is the variance of one observable less than or equal to that of another with respect to all quantum states?

György Pál Gehér, Nazar Miheisi

In quantum mechanics, the well-known Loewner order expresses that one observable's expectation value is less than or equal than that of another with respect to all quantum states.…
