Galois theory without functor... Without fundamental theorem of algebra. Are you kidding?
- stablemap 9y agoIt's a five page article in the Monthly, but I'd hesitate to include either topic even in a book.
- Ceezy 9y agoWhy? Whitout a clear explanation Galois functors you miss everything... And without the fundamental theorem of algebra, it's going to be very hard to have any real life example.
- JadeNB 9y ago> Galois theory without functor... The category-theoretic accretion to Galois theory is a much later addition; Galois certainly didn't think in those terms, and I think that it is not obligatory for an expository (or even a mathematical!) treatment of the subject to do so.
