Abstract Algebra: L1: a bit of history, definition of group, 8-29-2016

Incidentally, I meant to say "quintic" at the 10:30 or so time. That said, Galois theory has application to polynomials of any order.

Hello, professor! Thanks a lot for the great work you've been doing here. Greetings from Brazil!

[xoppa]

Brilliant teacher. Doesn't rush through theorems, and has nice discussions with students.

[rafaelprior]

still why the cancellation laws says multiply by the left on both sides? or right?

[welovfree]

Thank you, professor, for this sharing this lectures, my question is where can we find the assignments and test?

[MaxPicAxe]

"identity is not a spectrum, there's a single one"
"oh I'm sorry, was that a microaggression?"

Haha love you already

A bold declaration just at the beginning of this video which makes it to be different from all the rest of the math channels, I immediately subscribed it, praise the Lord!

[debojitsikdar]

This is really well put together. Most teachers won't touch on the intricacies of mathematics just to keep things simpler. Could I ask where can I get the pdfs used in this lecture and/or which book can I refer to?

[akcric]

Thank you for posting these online for people like myself to learn.

Great video .
Isn't Shridharacharya credited for giving formula for computation of roots of quadratic equation?
In India, we know this formula by his name only.

Hello Dr. Cook, Thank you for these videos and also the Algebraic Topology videos, I was wondering which book were you using for this Abstract Algebra course?
Thank you so much!

Professor I saw many abstract algebra series in your playlist in your channel, of 2017, 2018, 2019.o am watching this series of abstract algebra and another series of abstract algebra 2.so is this sufficient? Can u tell me?

[trangpho]

Do you have a textbook for this subject? I want documentaries!

[Sipnayan]

Thank you professor. What textbook are you using in this course?

[upscaspirant]

Thank you sir for uploading it for free, from Indian occupied Kashmir

Which edition of Gallian is he using for his Abstract Algebra 2016 notes?

[wreckim]

OT: Évariste Galois entire post on Wikipedia is like a novel, such a young and brilliant mind, and it even includes Alexander Dumas, as Galois is predicting his end in a duel. That whole period in France makes our political situation here in the U.S. look like child's play. BTW, what a great professor this guy is, such a calming nature to his lecture.

[BiscuitZombies]

Thank you. Finally a good series of lectures that wasn't recorded on a potato.

[dogwithwigwamz.]

`Then must all shapes correspond to a linear, quadratic, cubic, quartic, n` equation ?
... so that we have no option but to look out for and find some space and ascribe it to a Set of which the equation, n becomes entirely satisfactory ?

[Seastric]

and also if you could kindly make available your notes to the general public. possibly via a link on google drive.

23:29 what did he mean when he said this is a 400 level math course?
