Scientific Program

The goal of this workshop is to bring together researchers interested in numeration systems from various points of view. This includes geometric aspects (fractals, tilings, quasi-crystals), dynamical/probabilistic aspects (odometers, subshifts), analytic aspects (related arithmetical functions), topological aspects (compactifications and applications), and computer science (automata, languages). The workshop is intended as a continuation of the ``Journées Numération, Pavages, Substitutions'' held in Grenoble in March 2005. It is organised as part of the National Research Network ``Analytic Combinatorics and Probabilistic Number Theory'' supported by the Austrian Science Foundation. It is also closely related with the Action Concertée Incitative "Nouvelles Interfaces des Mathématiques".

Topics of the Conference



Special Issue of "Monatshefte für Mathematik"

The editors of Monatshefte für Mathematik have accepted to dedicate a special issue to this conference. We invite the participants to submit contributions. The deadline is August 31, 2007. Only original research papers will be accepted; in particular, the editors of Monatshefte do not intend to publish surveys.

Manuscripts should to be sent to as .dvi, .ps, or .pdf file until August 31, 2007. They will be refereed following the standards of Monatshefte für Mathematik.


With approximately 230.000 inhabitants, Graz is the 2nd largest city of Austria, situated in the region of Styria, 180 km (110 miles) south-west of Vienna. It has four universities (the University, the University of Technology,the Medical University of Graz, and the University of Music and Dramatic Arts), a pleasant old center that is not yet overcrowded by tourists, and nice hills and mountains nearby to the north, plus a wine growing area with rustic wineries to its south.

The Old Town of Graz is one of the best preserved in Europe and was awarded World Cultural Heritage by UNESCO in 1999. In 2003 Graz was European Cultural Capital.

The airport of Graz can be reached via Vienna, Frankfurt, Zurich, ... and some other "hubs". By train, it takes 2 hours and 40 minutes from Vienna.


Invited participants will be accomodated in the nearby Hotel Johannes, which is located in short walking distance from the conference venue. Room reservation can be done with the registration for the workshop. Please indicate dates of arrival and departure, single or double room. If you arrive after 10pm, please use the code that we will send out some days before the conference to open the key safe in front of the hotel.

How to reach the hotel:

Lunches will be served at the University Restaurant, which offers fast service and reasonable prices. There are some other restaurants in the area around the conference venue.


Wine tasting tour (approx. 35 € per Person). Visit to the wine growing area in the south of Styria. The tour includes a wine tasting, a drive through the scenic landscape, a visit to a pumpkin seed oil mill, and ends in a rustic tavern (Buschenschank), where dinner will be served.
