Localization of trigonometric polynomials and the Lev-Tselishchev lemma
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 Lp ( R) for p > ( 1 + 5 )/2 , is not carried over to small p.
