    I really like how you outline the ideas verbally before doing the algebra. Good job.

    In the near future, I believe the closest I might get to "real analysis" is a discussion of measure theory and Fourier analysis. Although I would love to talk about general real analysis and metric space theory (if that's what you're requesting), I already took that course in a previous term, so it's not too high on my priorities right now. You never know, though.

    Thanks. Unfortunately, at this point I am not qualified to speak about Fermat's Last Theorem.

    I’m currently studying free structures. This video is really helpful! Thanks!

    You probably want to look for an (at least slightly advanced) text on group theory. For example, "An Introduction to the Theory of Groups" by Joseph Rotman.

      Introduction to Group Theory by Oleg Bogopolski is also decent book.

    I seriously thought he said "absolute nonsense" in the beginning

    In the definition of free group. \phi: X->G

    This video has been so helpful. Can you do one on finitely generated Abelian groups? and the universal theorem?

    I believe I corrected one error on the board... is there one that I missed?

    I know this is pretty late, but this was really helpful! The state of group information on the internet is... surprisingly shit? Like, coming from self-researching topology and measure theory, it seems like the resources are just a lot less proof heavy, a whole lot of things stated but not given justification...

    Very well explained. I was having a bit difficulty in understanding by reading from books. Then I watched this video and everything was crystal clear. I even used some of your ideas in a students' presentation competition and bagged the 2nd prize. Thanku sir!
