... = ω ′ The automorphisms of Ω which are trivial on k form a group and so the above relation of conjugacy is an equivalence relation. We can therefore put elements of Ω into classes of conjugate ... as the kernel. Thus the prime ideal G is the same for a class of composite extensions. Conversely, if two composite extensions correspond to the same prime ideal of ¯ K, it...
