伽罗瓦理论第5版习题答案Galois Theory
=Ian Stewart - Galois Theory,  Fifth Edition [5th Ed] (Instructor Solution Manual, Solutions)
This Solutions Manual contains solutions to all of the exercises in the Fifth Edition of Galois Theory.
Many of the exercises have several different solutions, or can be solved using several different methods. If your solution is different from the one presented here, it may still be correct — unless it is the kind of question that has only one answer.
The written style is informal, and the main aim is to illustrate the key ideas involved in answering the questions. Instructors may need to fill in additional details where these are straightforward, or explain assumed background material. On the whole, I have emphasised ‘bare hands’ methods whenever possible, so some of the exercises may have more elegant solutions that use higher-powered methods.
