Streszczenie
Nyman and Beurling showed that the Riemann hypothesis is equivalent to the density of a certain function space in $L^2(0,1)$, called the Nyman–Beurling space. In this paper, we consider subspaces spanned by generators of the Nyman–Beurling space and give a necessary condition for the generators to be a fundamental set in $L^2(0,1)$.
