The Course

The course will discuss various aspects of modern algebra  concentrating on extending the linear algebra that you have already done and introducing some new abstract algebra in the form of group theory.

Generic skills

In addition to learning specific technical skills that will assist you in your future careers in science, engineering, commerce, education or elsewhere, you will have the opportunity to develop in this subject, generic skills that will assist you whatever your future career path.

  • You will develop problem-solving skills including engaging with unfamiliar problems, and identifying relevant strategies.
  • You will develop analytical skills - the ability to construct and express logical arguments and to work in abstract or general terms to increase the clarity and efficiency of the analysis.
  • Through practice classes and other interactions with fellow students, you will develop the ability to work in a team. The department distinguishes between ethical collaboration, which is strongly encouraged, and plagiarism, which is prohibited.

 

Assessment

There will be a three hour examination in the usual examination period at the end of the course.

There will also be

  • a mid-semester test which will take the form of a 50 minute test during the lecture time on Wednesday September 12.

and

  • two take-home assignments, one to be given out on Wednesday August 22 and the other on Wednesday October 17.

The final mark will be calculated as the maximum of

E and 0.1T+0.1A+0.8E

where T, A and E are the marks (out of 100) for your test, assignment and examination, respectively. That is, we will count the test and assignment marks if they improve your final mark but not otherwise.

 

Books

There is a set of lecture notes for the course; this includes some answers and solutions to exercises as well as solutions to old examination papers. These will be on sale at the Melbourne University Bookshop. I recommend that you consider buying a copy. It is not essential, however, as the topics are covered by many books both in the Library and for sale.

For those who do not want to buy a copy of the notes, the exercises will be available (free, of course) separately. The first set of exercises will also be available at the first lecture so that you can get started before obtaining the notes.

For those who do not buy the notes or who want more than the notes there are many books that make suitable reading.  If you are browsing in a library, look for books on Linear Algebra (but not a `first course') or Abstract Algebra or Group Theory.  The books listed below are recommended and will be on reserve in the mathematics library.

`Algebra' by Michael Artin (Prentice Hall, 1991)

`Finite dimensional vector spaces' by Paul R. Halmos (Springer, 1974)

`Groups and symmetry', by M. A. Armstrong (Springer, 1988)

'Abstract algebra' by Thomas Hungerford (Saunders College, 1990)

'Linear Algebra Done Right' by Sheldon Axler (Springer, 2002)

 

Practice Class

There will be weekly practice classes, starting in week 2 as given on your timetable from Allocate.

These are intended to give a more informal approach to the material of the course with more chance for discussion and questions. They will not introduce new material. It is expected that most students will want to come to only one class.

If you have any comments about how the course is going, please let me know. If you want to see me at any time (outside consultation hours), please contact email me (cdh AT ms.unimelb.edu.au).

Course Notes and Other Materials

You can view the notes on the internet from this screen. While the mathematical details may
not be as clear, there are some advantages in the form of links both within and without the document.

To view the notes, you will need the Adobe Acrobat Reader. If there is not one already on the machine you are using, it can be obtained free from Adobe. It is simple and convenient to use and you can print out any part of the notes if you wish.
 
The notes are available either as a single (long) document

 Notes for 620:222 Linear and Abstract Algebra

or in shorter parts. You will probably find it more convenient to take only the part you need at the time.

 

These electronic notes are actually from a previous year -- they are isomorphic to this year's notes.

Assignments will be handed out in class.
If you miss class please obtain one from my office (Room 172).
