Course description

This course will serve as an introduction to the concepts of Algebraic Topology, emphasis being homological methods, and with several applications. The main idea of algebraic topology is to assign algebraic invariants to topological spaces. These invariants are not only interesting in their own right but also capture geometric information.They are expected to be accessible during actual calculations. First example we will encounter is that of singular homology theory. Here the invariants are abelian groups. Towards the end of the course, we will study the closely related theory of singular cohomology. It turns out that singular cohomology with coefficients in a commutative ring carries more algebraic structure. For example, the product structure makes the singular cohomology of a space into a graded-commutative algebra.

Tests and Quizzes

There will be three in-class quizzes. There is a midterm for this course.
Quiz dates: 31st January, 14th March, 4th April

Homework 

The homework will be assigned every week. It is your duty to submit the solutions on time. Copying and/or plagiarism will not be tolerated. Here are a few writing guidelines you might want to follow.
  1. Feel free to work together, but you should submit your own work.
  2. Your questions/comments/suggestions are most welcome. I will also be fairly generous with the hints. However, do not expect any kind of help, including extensions, on the day a homework is due.
  3. Please turn in a neat stapled stack of papers. Refrain from using blank / printing paper. Use ruled paper.
  4. Your final finished version should be as polished as you can make it. This probably means that you cannot submit sketchy solutions or sloppily written first versions. Please expect to do a fair amount of rewriting. Do not hand in work with parts crossed out; either use a pencil and erase or rewrite.
  5. Please write complete sentences that form paragraphs and so forth. It might be a good idea to use short simple sentences; avoid long complicated sentences.
  6. Do use commonly accepted notation (e.g., for functions, sets, etc.) and never invent new notation when there is already some available.
  7. Make sure you provide a statement clearly indicating precisely what it is that you are about to prove. You can, if you want, label your statement as a Theorem or Claim or whatever. Write the word Proof, and then give your proof.
  8. Throughout your writing, constantly tell the reader (i.e. me, :-)) exactly what it is that you are about to demonstrate. Be sure to indicate the end of your proof.
  9. Your answers should combine “logic”, your hypotheses, and possibly other mathematical facts (e.g., theorems that we have proved in class) into an argument that establishes the asserted conclusion.
  10. Please be extra careful about the order in which you use your quantifiers.
  11. In your arguments you can make free use of anything that we have proven in class, and of course all logic rules and basic axioms and definitions. Anything else that you use should be proved.
The homework problems are assigned from the textbook.
