Показать описание
Field Theory: Let f(x) = x^4 -16x^2 +4. We find the roots of f(x), calculate the splitting field K of f(x) over Q in C, and determine the automorphism group of K.

This video was very good. I had been having problems understanding splitting fields, but you were very clear in this video and it was very helpful. The examples were extremely useful and well detailed.

Same here. You need function fields of prime characteristic to lose separable. I'm always in characteristic zero (differential geometry or real groups).
