There are no unconditional Schauder frames of exponentials in $L^{p}$ spaces, $p \neq = 2$

Nir Lev, Anton Tselishchev

We proved recently that there are no unconditional Schauder frames of exponentials in the space $L^{p} (Ω)$ , $1 \leq p < 2$ , for any set $Ω \subset R^{d}$ of finite measure. For…

A new example of crystalline-type measure with unit masses and an application to tiling of the real line by translates of a function

Anton Tselishchev

In this note we provide a simple explicit example of a discrete set $Λ \subset R$ of unbounded density such that the Fourier transform of its counting measure $δ_{Λ}$ …

Gabor unconditional bases and frames in $L^{p} (R)$

Nir Lev, Anton Tselishchev

We consider the following problem: given a set $Λ \subset R \times R$ and $p \neq = 2$ , does there exist a function $g \in L^{p} (R)$ such that the Gabor syste…

Weighted Chui's conjecture

Evgueni Doubtsov, Anton Tselishchev, Ioann Vasilyev

The goals of this paper are threefold. First, we show that a counterpart of the Newman bound related to the Chui conjecture is valid in the case where the gradient of Coulomb poten…

Unconditional Schauder frames of exponentials and of uniformly bounded functions in $L^{p}$ spaces

Nir Lev, Anton Tselishchev

It is known that there is no unconditional basis of exponentials in the space $L^{p} (Ω)$ , $p \neq = 2$ , for any set $Ω \subset R^{d}$ of finite measure. This is a consequence of a…

Completeness of sparse, almost integer and finite local complexity sequences of translates in $L^{p} (R)$

Nir Lev, Anton Tselishchev

A real sequence $Λ = {λ_{n}}_{n = 1}^{\infty}$ is called $p$ -generating if there exists a function $g$ whose translates ${g (x - λ_{n})}_{n = 1}^{\infty}$ span the space $L^{p} (R)$ . Whi…

Schauder frames of discrete translates in $L^{p} (R)$

Nir Lev, Anton Tselishchev

For every $p > (1 + 5) /2$ we construct a uniformly discrete real sequence ${λ_{n}}_{n = 1}^{\infty}$ satisfying $∣ λ_{n} ∣ = n + o (1)$ , a function $g \in L^{p} (R)$ , and conti…

Schauder frames of discrete translates in $L^{2} (R)$

Nir Lev, Anton Tselishchev

We construct a uniformly discrete sequence ${λ_{1} < λ_{2} < \dots} \subset R$ and functions $g$ and ${g_{n}^{*}}$ in $L^{2} (R)$ , such that every $f \in L^2(\mathbb{R}…

There are no unconditional Schauder frames of translates in $L^{p} (R)$ , $1 \leq p \leq 2$

Nir Lev, Anton Tselishchev

It is known that a system formed by translates of a single function cannot be an unconditional Schauder basis in the space $L^{p} (R)$ for any $1 \leq p < \infty$ . To the cont…
