Substitutions over infinite alphabet generating (-beta)-integers
Original language description
This contribution is devoted to the study of positional numeration systems with negative base introduced by Ito and Sadahiro in 2009, called (-?)-expansions. We give an admissibility criterion for more general case of (-?)-expansions and discuss the properties of the set of (-?)-integers. We give a description of distances within this set and show that this set can be coded by an infinite word over an infinite alphabet, which is a fixed point of a non-erasing non-trivial morphism.
