摘要
给出了两个扩域是φ-同构的一个充要条件、φ-同构的个数和有关证明。通过具体的实例展示了判别两个扩域是否为φ-同构的方法及此种同构的表示。
A necessary and sufficient condition is proved that two extension fields are φ-isomorphic.How to count the φ-isomorphisms and related proofs are also presented.Examples to show methods of classifying whether two extension fields are φ-isomorphic and representation of such isomorphism are presented.
