TMA4190 Introduction to Topology - Spring 2021
Dear all,
Find all information about the exam in the exam section. Due to the recent spike in the spreading of SARS-CoV-2 it seems as if NTNU will be forced to shut down its campus in Trondheim. Therefore, as a backup, I will create Zoom meetings for all of you having your exam in week 22 (possibly extended also to those of you having your exam in week 23 depending on what is decided and how long the new guidelines will be in effect).
Updated June 1, 10:30am: Oral exams may go ahead as planned. See here for further information. Notice the absolute requirement about NTNU Check-In. I ask that those of you wanting a Zoom exam notify me as soon as possible.
Please check this website for updated information. See also NTNUs website for SARS-CoV-2.
Best wishes,
Marius

What this course is about
This course is a first introduction to topology. It will start with basic concepts in point set topology (e.g. topological spaces, continuous maps, metric spaces, constructions of topological spaces, compactness, connectedness). Then it will give an introduction to algebraic topology, such as homotopy, fundamental group, and covering spaces. A short introduction to homology will give an outlook on computational methods.
See the study handbook for more information.
What you need to know before this course
You should have seen multivariate calculus and linear algebra. Ideally you should have taken TMA4150 Algebra and/or MA3201 Rings and Modules as well, but if you haven't don't worry!
If you have any questions, just contact me!
