Abstract

Uniform distribution is an important subject in classical Diophantine approximation. There is a close connection between the distribution of real numbers and the estimation of exponential sums via Weyl’s criteria. Carlitz gave a definition of uniform distribution in positive characteristic in an elementary way (see [11]), however, we are going to find a geometrical description. In this paper, we present a precise analogue to Weyl’s criteria in the case of positive characteristic by using Haar measure. As an application, we show that the uniformly distributed modulo 1 for linear forms and for polynomial functions. In particular, we prove the set in the Laurent series field is uniformly distributed modulo 1, where m extends over all the polynomials and is a fixed irrational function.
