Localization of trigonometric polynomials and the Lev-Tselishchev lemma

Published 2 Jul 2025 in math.CA | (2507.01521v1)

Abstract: The paper shows that the localization lemma used by N. Lev and A. Tselishchev in solving the problem of constructing quasi-bases from uniformly separated shifts of a function in the space $L^p (\mathbb R) $ for $ p > ( 1 + \sqrt 5 )/2 $, is not carried over to small $p$.
