We prove that in the real space $l_2(\mathbb Z)$ of two-sided sequences there is an element such that the sums of its shifts are dense in all real spaces $l_p(\mathbb Z)$, $2\le p\infty $, as well as in the real space $c_0(\mathbb Z)$.
Keywords: shift, two-sided sequences, approximation
Mots-clés : Fourier coefficients.
