It is truly astounding that anybody in the world can take a course taught by a fields medalist for free! What a time to be alive.

This is one of the best thing I have found in you tube. Thank you ❤️

Thank you so much for doing this professor!!! I believe that maybe not everyone who pursues mathematics ends up becoming a great mathematician, but a great mathematician can come from anywhere. Through this platform, you're reaching almost every part of the world, I hope somebody who needs this finds it!!

It is so truly nice to be taught group theory by a famed expert in group theory, Richard Borcherds himself!

Even tho I’m already familiar with basic group theory, this „lecture“ gives a nice perspective. Excellent „lecture“!

I'm just here to learn as a hobby. This lecture helped to clarify some things about groups (and representations) for me, it was really well presented. A few pennies dropped into place.

How I wish I could see your excellent videos when I was learning group theory.

I am a third year university student, I live in Vietnam. Thank you so much professor for making it easy for me to understand symmetry groups and properties of homomorphisms.

This is awesome, thank you so so much for taking the time to allow us to learn from one of the greatest minds alive.,

[keyvansalehi]

thanks dear professor for opening my eyes on math

[gopalvirsingh]

Sir it is truly a great privilege to watch your lectures

[PunmasterSTP]

This playlist is a really nice *group* of videos 👍

But seriously, I think the approach of using more examples than proofs is an outstanding one!

[basspuff]

I am proud to say I understand like 80% of this. Going to continue with this series and like rigorously concentrate. I want to understand this as deeply as possible. (12th grader)
