TMA4190 Introduction to Topology - Spring 2020

Dear all,

Updated May 25, 2020, 1:30pm

You should all have received an email from NTNU explaining the change of format and grades for the exam. Find the same information under the Exam section.

Please note the following:

  • The exam will be a digital home exam given on May 27, 9.00 - 13.00 (9am - 1pm).
  • Grades have been changed from A - F to pass/fail.
  • The exam will consist of a mixture of multiple choice problems and problems requiring you to show your work (see also the Exam section). Note that you will not be penalized for incorrect answers for the multiple choice problems.
  • The syllabus will consist of chapters 1 through 8 in the lecture notes. The intended material for chapter 9 will not be part of the syllabus.

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!

Informasjon om eksamen

Informasjon om eksamen

NTNU har vedtatt at det ikke skal arrangeres eksamen med fysisk oppmøte i april/mai/juni 2020. En rekke emner har på grunn av dette fått endret vurderingsform. En del emner har i tillegg endret karakterregel fra bokstavkarakter til bestått/ikke bestått.

TMA4190 - Introduksjon til topologi har endret vurderingsform. Vurderingen Skriftlig eksamen er endret til Hjemmeeksamen.

Karakterregel i emnet er endret til bestått/ikke bestått.

Emnebeskrivelsen og informasjon om vurdering i studentweb vil bli oppdatert innen 8.4.2020

  • Improvement of grade and change in form of grading
  • Deadline for cancellation of exam registration
  • Consequences of change in form of assessment from letter grading to pass/fail
  • Exam dates and duration
  • Special needs accomodation
  • Examination aids for home examination
  • Re-sit exam

If you still have questions, please contact the department using NTNU Help.

Good luck with the spring exam period!
With best regards,

The exam will consist of a mixture of multiple choice problems and problems that will require you to show your work. For problems that require you to show your work you can, e.g., write on a regular piece of paper and then either scan it or photograph it and upload it to your exam in Inspera Assessment. For further information about Inspera Assessment, please consult innsida.

See also here for information regarding digital home exams.

The syllabus for the exam will consist of chapters 1 through 8 in the lecture notes (including exercises).

I have prepared a trial exam for you to practice on. Try to work through it from start to finish without looking at the solutions.
