Abstract

We establish several new metrical results on the distribution properties of the sequence ({xn})n≥1, where {·} denotes the fractional part. Many of them are presented in a more general framework, in which the sequence of functions (xxn)n≥1 is replaced by a sequence (fn)n≥1, under some growth and regularity conditions on the functions fn.
