Journees Numeration or Numeration Conference series focus on properties of numeration systems.

• 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

Several surveys and books cover topics around Numeration Systems and their properties from many perspectives, among others we refers to:

• Formal Languages, Automata and Numeration Systems, by M. Rigo;
• Topological properties of Rauzy fractals Anne Siegel, Jörg M. Thuswaldner
• Physics and Theoretical Computer Science: From Numbers and Languages to (quantum) Cryptography Security Jean-Pierre Gazeau, Jaroslav Nešet&řil, Branislav Rovan, IOS Press, 2007.
