Digital expansion of exponential sequences

Michael Fuchs (2002)

Journal de théorie des nombres de Bordeaux

We consider the q -ary digital expansion of the first N terms of an exponential sequence a n . Using a result due to Kiss and Tichy [8], we prove that the average number of occurrences of an arbitrary digital block in the last c log N digits is asymptotically equal to the expected value. Under stronger assumptions we get a similar result for the first ( log N ) 3 2 - ϵ digits, where ϵ is a positive constant. In both methods, we use estimations of exponential sums and the concept of discrepancy of real sequences modulo 1 ...

Discrépance des suites de Farey

François Dress (1999)

Journal de théorie des nombres de Bordeaux

On étudie la discrépance absolue de la suite de Farey d’ordre n et on montre, en utilisant notamment une majoration d’une intégrale portant sur la fonction sommatoire de la fonction de Möbius, qu’elle est égale à 1 n exactement, ce qui est la valeur locale au point d’abscisse 1 n .

Discrepancy estimates for some linear generalized monomials

Roswitha Hofer, Olivier Ramaré (2016)

Acta Arithmetica

We consider sequences modulo one that are generated using a generalized polynomial over the real numbers. Such polynomials may also involve the integer part operation [·] additionally to addition and multiplication. A well studied example is the (nα) sequence defined by the monomial αx. Their most basic sister, ( [ n α ] β ) n 0 , is less investigated. So far only the uniform distribution modulo one of these sequences is resolved. Completely new, however, are the discrepancy results proved in this paper. We show...
