MATH6215 Algebra 2: Field extensions and Galois Theory

Offered By	Department of Mathematics
Academic Career	Graduate Coursework
Course Subject	Mathematics
Offered in	First Semester, 2012 and First Semester, 2013
Unit Value	6 units
Course Description	Just as there is a formula for solving a quadratic equation, there are similar formulae for solving the general cubic and quartic. Galois theory provides a solution to the corresponding problem for quintics --- there is no such formula in this case! Galois theory also enables us to prove (despite regular claims to the contrary) that there is no ruler and compass construction for trisecting an angle. Topics to be covered include: Galois Theory - fields Field extensions Normal extensions Separable extensions Revision of group theory, abelian and soluble groups Galois' Theorem Solubility of equations by radicals Finite fields Cyclotomic fields Note: Graduate students attend joint classes with undergraduates but will be assessed separately.
Learning Outcomes	On satisfying the requirements of this course, students will have the knowledge and skills to: 1. Explain the fundamental concepts of field extensions and Galois theory and their role in modern mathematics and applied contexts 2. Demonstrate accurate and efficient use of field extensions and Galois theory 3. Demonstrate capacity for mathematical reasoning through analyzing, proving and explaining concepts from field extensions and Galois theory 4. Apply problem-solving using field extensions and Galois theory applied to diverse situations in physics, engineering and other mathematical contexts.
Indicative Assessment	Assessment will be based on: Assignment 1 (20%; LO 1-4) Assignment 2 (20%; LO 1-4) Assignment 3 (20%; LO 1-4) Final exam (40%; LO 1-4)
Workload	36 lectures, tutorials by arrangement
