## Marco Pedicini.
Greedy expansions and sets with deleted digits.

We generalize a result of Daróczy and Kįtai,
on the characterization of univoque numbers with
respect to a non-integer base [DaróczyKįta1985]
by relaxing the digits alphabet to a generic set of
real numbers. We apply the result to derive the
construction of a Büchi automata accepting all and
only the greedy sequences for a given base and digit
set. In the appendix we prove a more general version of
the fact that the expansion of an element *x*in *QQ*(*q*)
is possibly periodic, if *q* is a Pisot number.
