Summary  This is a course in abstract algebra, although connections with other fields will be stressed as often as possible. It will cover some of the jewels in the crown of undergraduate mathematics, drawing together groups, rings and fields to solve problems that resisted the efforts of mathematicians for many centuries. The powerful central ideas of this course are now crucial to many modern problems in algebra, differential equations, geometry, number theory and topology.

Learning Outcomes
On completion of this course, the student will be able to:
 Demonstrate facility with fields and their extensions, including expertise in explicit calculations with and constructions of examples with various relevant desired properties.
 Handle Galois groups, abstractly and in explicit examples, by using a variety of techniques including the Fundamental Theorem of Galois Theory and presentations of fields.
 Explain and work with the consequences of Galois Theory in general questions of mathematics addressed in the course, such as insolubility of certain classes of equations or impossibility of certain geometric constructions.
 Produce examples and counterexamples illustrating the mathematical concepts presented in the course.
 Understand the statements and proofs of important theorems and explain the key steps in proofs, sometimes with variation.
