Read: Finish reading Chapter 6.
- Example 6.73 is really important for the problems that follow, so please read it carefully.
Turn in: 6.71, 6.74, 6.76, 6.79, 6.80
- For 6.71 you mainly just need to use the definition of Aut(K/F) which is Aut(K/F)={α∈Aut(K)∣∀f∈F,α(f)=f}.
- When doing 6.80(4), read over 6.72 about why the subgroup lattice is upsidedown.
Extra practice: 6.70, 6.72, 6.77
