Course Description

 

We understand this course as a comprehensive beginners course in algebraic topology. Although it is helpful to have taken Topologie I to follow the present course, it is not necessary. The aim of Topologie II is for you to thoroughly understand and be able to apply all notions of homology and cohomology, the cup and cross product, as well as some results on duality (for instance Poincaré duality). The course will roughly be structured as follows (as time permits):

  • Categories and functors, chain complexes

  • Singular homology, chain homotopy

  • Mayer-Vietoris Sequence, Jordan Curve Theorem

  • Reduced homology, relative homology, Alexander's theorem

  • Simplicial homology

  • Degrees, Euler characteristic, Lefschetz number, Lefschetz fixed point theorem

  • CW complexes

  • Cellular homology

  • Eilenberg–Steenrod axioms

  • Künneth Theorem

  • Universal Coefficient Theorem

  • Singular cohomology, simplicial cohomology

  • Cup product

  • Cross product, topological manifolds

  • Poincaré Duality

  • Alexander Duality

  • Manifolds with boundary

We recommend the books by J. Munkres ("Elements of Algebraic Topology", Addison-Wesley 1984) and A. Hatcher ("Algebraic Topology", Cambridge U Press 2002, also online) and the succinct lecture notes by J. P. May ("A Concise Course in Algebraic Topology", online).

Mon14:15 - 15:45SR 031, Arnimallee 6

In the tutorial, we will learn some things that will help us better understand the lecture, expand on topics from class, and occasionally review exercises.

Every week now and then a sheet will appear on this website containing 3-8 exercises, some of which we highly recommend. Do the other exercises if they seem challenging enough or if you don't have an idea of how to solve them immediately. Solutions to the highly recommended and challenging select exercises will appear on this website a week later. In order to encourage you to solve exercises, we will (1) periodically ask students to present solutions to an exercise in the tutorial and (2) base parts of the exam on the exercises.

Course requirements are the following: (1) You must actively participate in the course. (2) You must pass an exam at the end of the semester which alone will determine your grade. The date for the exam will be set within the first 2 weeks of class.. The first written exam will take place on March 3 from 2-4 PM in "Großer Hörsaal Informatikgebäude Takustraße 9". The second written exam will take place on April 13 from 10AM - 12PM in "Seminarraum Animallee 2".
