Summary.
-
The second part of considerations concerning
groups and fields. It includes a definition and properties of
commutative field $F$ as a structure defined by: the set, a support
of $F$, containing
two different elements, by two binary operations
${\bf +}_{F}$, ${\bf \cdot}_{F}$ on this
set, called addition and multiplication, and by two elements from
the support of $F$,
${\bf 0}_{F}$ being neutral for addition and
${\bf 1}_{F}$ being neutral for
multiplication. This structure is named a field if
$\langle$the support of $F$, ${\bf +}_{F}$, ${\bf 0}_{F} \rangle$
and
$\langle$the support of $F$, ${\bf \cdot}_{F}$, ${\bf 1}_{F} \rangle$
are commutative groups and multiplication
has the property of left-hand and right-hand distributivity with respect to
addition. It is demonstrated that the field $F$ satisfies the definition of
a field in the axiomatic approach.
