This unit aims to provide an introduction to the algebraic structures of rings and fields, describing the quotient structure and its connection with homomorphisms of rings and presenting important examples with particular emphasis on polynomial rings.
On the successful completion of the course, students will be able to:
- Describe and apply properties of primes and division in the integers.
- Define rings, domains and fields and describe standard examples.
- Recognise and construct special types of elements in rings and fields.
- State and recall proofs of properties of rings and ring homomorphisms and apply these to standard examples.
- Recognise ideals and use ideals to construct factor rings.
- Describe properties of polynomial rings and calculate factors and greatest common divisors of polynomials over a field.
- Describe Kronecker’s Theorem and use it to construct roots of polynomials and field extensions.
