Rome 5-9 June 2017 - Argiletum in Madonna dei Monti

The goal of this workshop is to bring together researchers interested in interactions between numeration systems, ergodic theory, number theory and combinatorics.


Conference Topics

General numeration systems Geometric representations, Rauzy fractals, tilings Representations of operations in Pisot base by finite automata Sofic systems associated with Pisot numbers Redundant representations and cryptography Shift-radix systems Abstract number systems Beta-integers and their combinatorial properties Spectra and spectral measures associated with numeration Sums of digits for classical and non-classical numerations, associated fractals Analytic and probabilistic study of arithmetic functions related to numeration Combinatorics on words and Diophantine approximation Algebraic and transcendental numbers linked with beta-numeration

Abstract Submission

Abstract submission should be sent to the Conference submission page at EasyChair Numeration2017.

Conference Schedule

The conference open on Monday 5/6/2017 morning and ends on Friday 9/6/2017.


The conference will take place in the Roma Tre University - Argiletum at the Urbano VIII Conference Room.

Address: via Madonna dei Monti 40, Rione Monti, Roma. The Argiletum is the building on the left side of the Madonna dei Monti Church.

It is a wonderful location at the very historical heart of Rome. It is reacheable by 5min walk from the Cavour underground station (Metro - Linea B).

We wish to remind you that we are unable to support travel or living expenses.


Rione Monti, as it is called the area surrounding the Argiletum, provides a large selection of accommodations of all sorts (Hotels, B&B and so on), see the accommodation page.

Organizing Committee

Corrado Falcolini (Roma Tre University), Anna Chiara Lai (La Sapienza University of Rome), Roberto Maieli (Roma Tre University), Valerio Talamanca (Roma Tre University)
