The Zeckendorf expansion of polynomial sequences

Michael Drmota, Wolfgang Steiner (2002)

Journal de théorie des nombres de Bordeaux

In the first part of the paper we prove that the Zeckendorf sum-of-digits function s z ( n ) and similarly defined functions evaluated on polynomial sequences of positive integers or primes satisfy a central limit theorem. We also prove that the Zeckendorf expansion and the q -ary expansions of integers are asymptotically independent.

Topological properties of two-dimensional number systems

Shigeki Akiyama, Jörg M. Thuswaldner (2000)

Journal de théorie des nombres de Bordeaux

In the two dimensional real vector space 2 one can define analogs of the well-known q -adic number systems. In these number systems a matrix M plays the role of the base number q . In the present paper we study the so-called fundamental domain of such number systems. This is the set of all elements of 2 having zero integer part in their “ M -adic” representation. It was proved by Kátai and Környei, that is a compact set and certain translates of it form a tiling of the 2 . We construct points, where...

Transformations preserving the Hausdorff-Besicovitch dimension

Sergio Albeverio, Mykola Pratsiovytyi, Grygoriy Torbin (2008)

Open Mathematics

Continuous transformations preserving the Hausdorff-Besicovitch dimension (“DP-transformations”) of every subset of R 1 resp. [0, 1] are studied. A class of distribution functions of random variables with independent s-adic digits is analyzed. Necessary and sufficient conditions for dimension preservation under functions which are distribution functions of random variables with independent s-adic digits are found. In particular, it is proven that any strictly increasing absolutely continuous distribution...
