Research output: Contribution to journalArticlepeer-review


Let (Formula presented.) be a lacunary sequence of positive real numbers. Rudnick and Technau showed that for almost all (Formula presented.), the pair correlation of (Formula presented.) mod 1 is Poissonian. We show that all higher correlations and hence the nearest-neighbour spacing distribution are Poissonian as well, thereby extending a result of Rudnick and Zaharescu to real-valued sequences.
