Further information on descriptions Description: Aims:
To introduce the students to basic abstract ring theory and provide a thorough structure theory of linear operators on a finite dimensional vector spaces.

Learning Outcomes:
After taking this unit, students should be able to:
* Demonstrate understanding of the basic theory of rings.
* Factorise in various integral domains they have met throughout the course and demonstrate understanding of the general theory.
* State and prove the fundamental results on the structure theory of linear operators.
* Apply the structure theory of linear operators in examples. Determine characteristic polynomials, minimal polynomials, geometric and algebraic multiplicities as well as the Jordan normal form for a given linear operator. Calculate generalised eigenspaces.

Skills:
Numeracy T/F A
Problem Solving T/F A
Written and Spoken Communication F (in tutorials).

Content:
