| Dec 17, 2010 at 10:54 | comment | added | Kevin H. Lin | I recently (re)read the sections of Dummit-Foote on Galois theory. I think it was stated therein that Abel found the first proof of the insolvability of the quintic, but it was Galois who found the general method involving group theory for proving the solvability or insolvability of any polynomial. I don't recall if Dummit-Foote elaborates on Abel's method, but presumably it doesn't generalize like Galois's method does. | |
