Congratulations to the four of you who took the exam! The grades were excellent, and I am very happy to see that you all have such a good feeling for and understanding of topology!

I have now marked the exams. I am delighted with the results! The vast majority of you achieved a thoroughly deserved A or B. I am very happy to see that you have all worked so hard and have learnt so much!

Now that the last lecture has been given, I would just like to thank all of you for your participation. It has truly been a pleasure teaching you, I have enjoyed it greatly. I'm sure that you will all do very well on the exam — I very much hope that you will do so, and wish you the best of luck!

The mock exam is in the same style as the real exam will be. The questions are overall perhaps slightly more difficult than those which will be asked on the real exam.

About half a question more on the real exam compared to the mock exam will be taken from the knot theory and surfaces part of the course.

A third revision class on knot theory and surfaces took place on Wednesday, 22/05.

It is very important that you understand all of the solutions from the classes, except any which are marked as non-examinable. Just let me know if not, and I will be happy to help.

This has now been updated to cover the entire course.

Reidun Persdatter Ødegaard and Therese Mardal Hagland represented you.

A third and last meeting took place after the exam.

Thanks very much to Reidun and Therese for an excellent job!

If you have any questions, or if there's anything that you do not follow, please feel free to ask me.

All the lectures on knot theory have now been uploaded, as well as all the examinable lectures from the first part of the course.

I plan to combine the remaining lectures on surfaces into one. I have uploaded a few excerpts.

If you know Latex, you are welcome to edit the source files for the lectures. For example, it is possible to make annotations. Here are the files for Lectures 1 – 14. tar

This is a tarball, which needs to be extracted. The file which needs to be compiled (with pdflatex) is 'generell_topologi.tex'.

If you have any questions on how to compile or edit the source files, please feel free to ask me.

I have not yet had time to carefully proof read the solutions to Exercise Sheet 3, and a few pictures are missing. I have made them available in case they are nevertheless helpful.

Just let me know if you cannot understand any of the solutions, and I will do my best to help! If you spot a mistake, please also get in touch!

In the exercise classes I will discuss the exercise sheets and the lectures with you, in a more informal setting than the lectures.

Attendance is entirely optional.

Topology is the study of topological spaces, which are of indispensable importance across mathematics, and are equally important in physics, computer science, and other disciplines.

If the idea of studying gadgets such as knots, the Möbius band, the Klein bottle, or of turning a sphere inside out, intrigues you, or if you are baffled as to how a hundred year old problem proven recently can be of a completely different flavour in three and four dimensions than in five or more, this course is where you should start!

If you have enjoyed courses in analysis, geometry, or algebra, or any combination of these, it's likely that you'll find something to your taste in topology — it's a rich and diverse subject, and further study can lead in any or all of these directions.

This course will have two goals:

- To introduce examples of topological spaces, illustrating various phenomena, and conveying something of topology's geometric flavour.
- To develop the foundations of topology relied upon in higher courses.

Upon successful completion of the course, you will have acquired knowledge which will open up doors to higher courses, and will have developed skills — the suppleness of mind needed to understand topological pheneomena intuitively; an ability to reason at a more abstract level than you have probably come across before; the organisation and discipline necessary to match topological intuition to abstract rigour — which will be valuable to you in your chosen career.

The lectures will be given in English.

The official course description may be found here.

There are no formal pre-requisite courses, but most of the mathematics courses you have taken previously would likely be helpful in one way or another.

There is no obligatory textbook — the examination will be based upon the contents of the lectures and the exercise sheets.

However, the following textbook is recommended if you are looking for a book to support the lectures. The bookstore will order 10 copies.

M.A.Armstrong, * Basic Topology. *

There are many other textbooks which you may find helpful. A brief guide can be found above.

You are welcome to contact me by email or to come to my office at any time to discuss anything from the lectures that you did not follow, or anything else.

My email address can be found here.

My office is 1248, Sentralbygg 2. On the door it says Andrew Stacey (i.e. not my name!).
