On the law of the iterated logarithm for the discrepancy of 〈nkx〉

چکیده
By a well known result of Philipp (1975), the discrepancyDN (ω) of the sequence (nkω)k≥1 mod 1 satisfies the law of the iterated logarithm under the Hadamard gap condition nk+1/nk ≥ q > 1 (k = 1, 2, . . .). Recently Berkes, Philipp and Tichy (2006) showed that this result remains valid, under Diophantine conditions on (nk), for subexpenentially growing (nk), but in general the behavior of (nkω) becomes very complicated in the subexponential case. Using a different norming factor depending on the density properties of the sequence (nk), in this paper we prove a law of the iterated logarithm for the discrepancy DN (ω) for subexponentially growing (nk) without number theoretic assumptions.

By a classical result of Philipp (1977), for any positive sequence (nk)k≥1 satisfying the Hadamard gap condition, the discrepancy of (nkx)1≤k≤N mod 1 satisfies the law of the iterated logarithm. For sequences (nk)k≥1 growing subexponentially this result becomes generally false and the asymptotic behavior of the discrepancy remains unknown. In this paper we show that for randomly sampled subsequ...

By a classical result of Weyl (1916), for any increasing sequence (nk) of positive integers, (nkx) is uniformly distributed mod 1 for almost all x. The precise asymptotics of the discrepancy of this sequence is known only in a few cases, e.g. for nk = k (Khinchin (1924)) and for lacunary (nk) (Philipp (1975)). In this paper we extend Philipp’s result to lacunary sequences with multidimensional ...

We establish a law of the iterated logarithm for the discrepancy of sequences (nkx) mod 1 where (nk) is a sequence of integers satisfying a sub-Hadamard growth condition and such that one and four-term Diophantine equations in the variables nk do not have too many solutions. The conditions are discussed, the probabilistic details of the proof are given elsewhere. As a corollary to our results, ...

A classical result of Philipp (1975) states that for any sequence (nk)k≥1 of integers satisfying the Hadamard gap condition nk+1/nk ≥ q > 1 (k = 1, 2, . . .), the discrepancy DN of the sequence (nkx)k≥1 mod 1 satisfies the law of the iterated logarithm (LIL), i.e. 1/4 ≤ lim supN→∞NDN (nkx)(N log logN)−1/2 ≤ Cq a.e. The value of the limsup is a long standing open problem. Recently Fukuyama expli...
