Summary.
-
In the article the following concepts were introduced:
the set of integers (${\Bbb Z }$)
and its elements (integers),
congruences ($i_1 \equiv i_2 (\mathop{\rm mod} i_3)$),
the ceiling and floor functors ($\mathopen{\lceil} x \mathclose{\rceil}$ and
$\mathopen{\lfloor} x \mathclose{\rfloor}$), also
the fraction part of a real number (frac),
the integer division ($\div$) and remainder of integer division (mod).
The following schemes were also included:
the separation scheme ({\it SepInt}),
the schemes of integer induction ({\it Int\_Ind\_Down},
{\it Int\_Ind\_Up}, {\it Int\_Ind\_Full}),
the minimum ({\it Int\_Min}) and maximum ({\it Int\_Max}) schemes (the
existence of minimum and maximum integers enjoying a given property).
