Anello de division
Un anello de division [ 1] es un structura algebric con duo operationes.
Definition
Un anello de division es un insimul
R
{\displaystyle R}
con duo operationes binari e interne
+
{\displaystyle +}
e
⋅
{\displaystyle \cdot }
(que es nominate addition e multiplication ), pro que vale le conditiones sequente
(
R
,
+
)
{\displaystyle \left(R,+\right)}
es un gruppo abelian (con le elemento neutre
0
{\displaystyle 0}
)
(
R
∖
{
0
}
,
⋅
)
{\displaystyle \left(R\setminus \left\{0\right\},\cdot \right)}
es un gruppo (con le elemento neutre
1
{\displaystyle 1}
)
le leges distributive:
a
⋅
(
b
+
c
)
=
a
⋅
b
+
a
⋅
c
{\displaystyle a\cdot \left(b+c\right)=a\cdot b+a\cdot c\,}
pro omne
a
,
b
,
c
∈
R
{\displaystyle a,b,c\in R}
(
a
+
b
)
⋅
c
=
a
⋅
c
+
b
⋅
c
{\displaystyle \left(a+b\right)\cdot c=a\cdot c+b\cdot c\,}
pro omne
a
,
b
,
c
∈
R
{\displaystyle a,b,c\in R}
Si le multiplication es additionalmente commutative (a saper le gruppo
(
R
∖
{
0
}
,
⋅
)
{\displaystyle \left(R\setminus \left\{0\right\},\cdot \right)}
es abelian), iste anello es un corpore .
Corpore
Alicun autores usa le nomine corpore pro anellos de divsion; ergo illes nomina un corpore corpore commutative .
