WebThen, our main theorem says that the norm theorem of K F is derived from the class field isomorphism ~ . CK DK =GK Usually, the norm theorem is proved in the process of constructing the class field theory. But, our result has its own meaning, since it gives us a way to a new, geometric foundation of the class field theory. 0. Introduction
