Further Information

Let \(b_1, b_2, \dots \) be an arbitrary infinite sequence of positive integers and \(\alpha \) any positive real number. It is proved that the collection of all sums of type \(\sum \varepsilon (m,n) b_m [ 2^n \alpha ] \) with \(\varepsilon (m,n)=0\) or 1 always contains an infinite arithmetic progression (i.e. the sequence is subcomplete).
