MA3002 General Topology - Spring 2016

• I have uploaded the file szymik.MA3002.pdf that has the notes for the course.

• I have uploaded the file exam2016.pdf that has the exam problems with hints for solutions.

• There will be no lecture on Tuesday, March 8th.
• The first meeting will be on Tuesday, January 12th.
• Actually this and the one above have good chances to be the only messages that will appear here during the course, because of I will try to use itslearning for a lot of communication in this course.

• I have already established two forums, one for questions concerning the formal aspects of this course, and one for the purpose of discussing the mathematics. Please make ample use of them.
• And now there are also two links: One to this page, and on to the lecture notes. Warning: Don't get excited! As of now, it's not much more than a copy of the table below. The actual contents will be filled in as the course proceeds…

• Course description

• Tuesdays, 10:15 - 12:00, KJL24 R54
• Thursdays, 12:15 - 14:00, KJL21 G21

• Markus Szymik
• Office: 1252, Sentralbygg II
• Hours: On Tuesdays after the lecture. Whenever you have a question, don't hesitate to come by my office and ask me.

I intend that

• notes for the course

are produced. Details will be supplied in the lectures.

Here is a (freely available) set of notes that points out a lot of applications of topology to real world problems.

• R. Ghrist. Elementary applied topology. 2014. (Appendix: Background)
  www.math.upenn.edu/~ghrist/notes.html

Therefore we will not have to work with a text book. There is, however, an official course text:

• J.R. Munkres. Topology. 2nd ed. Prentice Hall, 2000.

The following (parts of) books may also be useful for the purposes of the course.

• N. Bourbaki. Topologie générale. Hermann & Cie., 1940 and later. (in French)
• G.E. Bredon. Topology and geometry. Springer-Verlag, New York, 1993. (Chapter I and Appendix)
• T. tom Dieck. Algebraic topology. European Mathematical Society, Zürich, 2008. (Chapter 1)
• G. Laures, M. Szymik. Grundkurs Topologie. 2. Aufl. Springer Spektrum, Heidelberg, 2015. (in German)
• L.A. Steen, J.A. Seebach. Counterexamples in Topology. Reprint of the second (1978) edition. Dover Publications, 1995.

More references will be added here when they become relevant.

The syllabus is defined in terms of the official course text.
