# Course syllabus - Abstract Algebra 7.5 credits

### Abstrakt algebra

 Course code: MMA501 Valid from: Autumn semester13 Autumn semester14 Level of education: Second cycle Subject: Mathematics Main Field(s) of Study: Mathematics/Applied Mathematics, In-Depth Level: A1N (Second cycle, has only first-cycle course/s as entry requirements), School: UKK Ratification date: 2013-02-01 Change date: 2014-02-02

## Objectives

Algebra is one of the fundamental branches of modern mathematics. It has its origins in the theory of numbers and geometry. The aim of the course is to find, through examples, the mathematical structures underlying concepts in number theory and geometry. These structures, groups, rings and fields, are applied in multiple contexts such as counting and enumeration problems, coding theory and combinatorial designs.

## Learning outcomes

After completing the course the student should be able to

- using set theoretical language define and give examples of the basic structures and fundamental concepts of algebraic theory, and appropriately use the formal language of the theory in speech and writing
- formulate, interpret and give examples of the basic facts and constructions of the theory
- using formal reasoning prove or disprove the simple statements in the theory
- place the theory in its context in mathematical history and give examples of the connection between algebraic theory and other branches of Mathematics such as geometry or analysis

## Course content

- Sets, equivalence relations
- Groups: subgroups, permutation groups, cyclic groups, cosets, direct product, Abelian groups, honomorphisms, quotient groups, simple groups
- Rings and fields: integral domains, ideals, homomorphims and quotient rings. Maximal ideals, polynomial rings, factorization, field of quotients of an integral domain
- Field extensions: algebraic extensions, constructibility. Finite fields.
- Coding theory

## Specific entry requirements

120 credit points in Engineering, Natural Science, Business Administration, or Economics, including at least two of the courses Vector Algebra 7.5 credit points, Discrete Mathematics 7.5 credit points, Linear Algebra 7.5 credit points, or the equivalent. In addition, Swedish B/Swedish 3 and English A/English 6 are required. In cases when the course is offered in English, the requirement for Swedish B/Swedish 3 is excluded.

## Examination

Final exam, written and/or oral (TEN1), 7.5 credits, marks 3, 4 or 5, Final exam, written and/or oral. May be partially or fully replaced by written assignments.

A student who has a certificate from MDH regarding a disability has the opportunity to submit a request for supportive measures during written examinations or other forms of examination, in accordance with the Rules and Regulations for Examinations at First-cycle and Second-cycle Level at Mälardalen University (2016/0601). It is the examiner who takes decisions on any supportive measures, based on what kind of certificate is issued, and in that case which measures are to be applied.

Suspicions of attempting to deceive in examinations (cheating) are reported to the Vice-Chancellor, in accordance with the Higher Education Ordinance, and are examined by the University’s Disciplinary Board. If the Disciplinary Board considers the student to be guilty of a disciplinary offence, the Board will take a decision on disciplinary action, which will be a warning or suspension.
