Let a=(a1, a2, a3, ...) be an arbitrary infinite sequence in U=[0, 1). Let

Van der Corput [5] conjectured that d(a, n) (n=1, 2, ...) is unbounded, and this was proved in 1945 by van Aardenne-Ehrenfest [1]. Later she refined this [2], obtaining

for infinitely many n. Here and later c1, c2, ... denote positive absolute constants.
In 1954, Roth [8] showed that the quantity

is closely related to the discrepancy of a suitable point set in U2.
