Miscellaneous
Jan 7: Ever wondered what a polytope is? I am organizing this semester a learning seminar on polytopes starting Jan.16. Send me an email if you are interested! (Only prerequisite is linear algebra and commitment).
This beautiful article will show you a broader perspective of mathematics as a whole.
Jan 8: The Institute for Advance Studies has this nice workshop for women in math next spring. The only prerequisites are group theory and t opology. I encourage the women in this class to apply!


LaTeX and other resources:
You can download LaTeX here depending on your operating system. For Windows, download the proTeXt version. The template used in Homework 1 is here.

There are several online resources on how to write mathematical proofs. Here you find a short manuscript with some proving techniques. Here you can find a more extensive approach.
