Introduce the concepts of rings and fields in abstract algebra, discussing the properties of ring elements, ring homomorphisms, ideals, integral domains, and fields.
Rings and Fields Definition of a Ring A set R with two operations (addition and multiplication) where R is an abelian group under addition, multiplication is associative, and multiplication distributes over addition. Commutative Rings A ring where multiplication is also commutative (ab = ba for all a, b in R). Rings with Unity A ring that has a multiplicative identity element (usually d...…
