NettetIn the present chapter we introduce the basic concepts of integral domain, division ring, field, ideal, difference ring, isomorphism, homomorphism and anti-isomorphism. Also we introduce some important special instances of rings such as matrix rings and quaternions. Finally we prove the analogue for rings of Cayley’s theorem on groups.

NettetA domain is called normal if it is integrally closed in its field of fractions. Lemma 10.37.2. Let be a ring map. If is a normal domain, then the integral closure of in is a normal domain. Proof. Omitted. The following notion is occasionally useful when studying normality. Definition 10.37.3. Let be a domain. In mathematics, specifically abstract algebra, an integral domain is a nonzero commutative ring in which the product of any two nonzero elements is nonzero. Integral domains are generalizations of the ring of integers and provide a natural setting for studying divisibility. In an integral domain, every … Se mer An integral domain is a nonzero commutative ring in which the product of any two nonzero elements is nonzero. Equivalently: • An integral domain is a nonzero commutative ring with … Se mer The following rings are not integral domains. • The zero ring (the ring in which $${\displaystyle 0=1}$$). • The quotient ring $${\displaystyle \mathbb {Z} /m\mathbb {Z} }$$ when m is a composite number. … Se mer The field of fractions K of an integral domain R is the set of fractions a/b with a and b in R and b ≠ 0 modulo an appropriate equivalence relation, equipped with the usual … Se mer • The archetypical example is the ring $${\displaystyle \mathbb {Z} }$$ of all integers. • Every field is an integral domain. For example, the field $${\displaystyle \mathbb {R} }$$ Se mer In this section, R is an integral domain. Given elements a and b of R, one says that a divides b, or that a is a divisor of b, or that b is a multiple of … Se mer • A commutative ring R is an integral domain if and only if the ideal (0) of R is a prime ideal. • If R is a commutative ring and P is an ideal in R, then the quotient ring R/P is an integral domain if and only if P is a prime ideal. Se mer Integral domains are characterized by the condition that they are reduced (that is x = 0 implies x = 0) and irreducible (that is there is only one minimal prime ideal). The former condition ensures that the nilradical of the ring is zero, so that the intersection of all the ring's … Se mer general international group
