Abstract:
In this paper the lattice of definability for integers with a successor (the relation $y = x + 1$) is described. The lattice, whose elements are also knows as reducts, consists of three
(naturally described) infinite series of relations.
The proof uses a version of the Svenonius theorem
for structures of special form.
Keywords:
definability, reducts, Svenonius theorem.
