Cool trio of vids using Galois Theory to solve an example cubic equation, hope you enjoy:
He also has a playlist deriving the Abel-Ruffini theorem which is great but pretty long.
Why just a cubic?
Why not a more interesting, say quintic or above, with solvable Galois group?
Every cubic is solvable so I don't see how this is that interesting.
It is kinda interesting, but could have been better.
guys could you tell a pleb where he could study abstract algebra and where I could see a list of prerequisites that I need to learn before I dive in?
Thanks then, I didn't bother looking it up because I don't have access to Jstor already.
But looks it's popular enough that many people uploaded it.
And it's by Dummit, cool.
Dummit & Foote, Hernstein, or Artin's.
If you want a really cool and easy presentation with a lot of interesting problems, pick Artin's.
If you want a thorough explanation of the whole problem with shit ton of problems and almost anything that you can think of as an undergrad, Dummit.
Hernstein is in-between, but much closer to Artin.
I'd suggest Artin first.
I'm assuming you mean this one. already got it from libgen and I'm going to start reading it tonigt. thanks friend
