Abstract
Let A be a class of real valued integrable functions on [0,1). We will call a strictly increasing sequence of natural numbers a = (a(r))(r=1)(infinity ) an A* sequence if for every f in A we have lim(n --> infinity) (1)/(n) Sigma (n)(r=1) f(<a(r)x >) = integral (1)(0) f( t)dt, almost everywhere with respect to Lebesgue measure. Here, for a real number ), we have used <y > to denote the fractional part of y. For a finite set A we use /A/ to denote its cardinality. In this paper we show that for stric tly increasing sequences of natural numbers a = (a(r))(r=1)(infinity) and b = (b(s))(s=1)(infinity), both of which are (L-P)* sequences for all p >1, if there exists C > 0 such that /{r : a(r) less than or equal to u} // {s : b(x) less than or equal to u}/ less than or equal to C/{(r, s) : a(r)b(x) less than or equal tou}/, (u = 1 , 2, ...) then the sequence of products of pairs of elements in a and b once ordered by size is also an (L-p)* sequence.
