Abstract

Let J1, . . . , J k ⊆ [0, 1) be finite unions of intervals, P1(x), . . . , P k (x) ∈ R[x] of degree at least one, Qm1,...,mk (x) = m1P1(x) + . . . + m k P k (x), m1, . . . , m k ∈ Z. Assume that Qm1,...,mk (x) − Qm1,...,mk (0) has at least one irrational coeffi- cient for every (m1, . . . , m k )= (0, . . . , 0). Let S := {n | n ∈ N, {P (n)} ∈ J , l = 1, . . . , k}, λ = Lebesgue measure. We l l shall prove the following theorem. Under the conditions stated aboveg∈ su M p 1x 1 n≤x g(n) − λ(J1) . . x .
